    Timing chain cover removal

    I have a 2.5l v6 in my svt and I need to know what all has to be removed to take off the timing chain cover

    Engine compression

    Hello Dom, That's the most direct answer that could explain all this... Is information available about this? I mean, is it documented somewhere? how about the correct way to synchronize it? Regards

    Engine compression

    I would make sure engine timing (timing chains) is correct since it's been apart before for the head gasket replacement. The early model 2.5L's had false flags on the cams that people would line up and the engine would run poorly and could have poor compression as the valve timing would be out of sync from the crank timing. -Dom

    Engine compression

    I found this post Dom states that the proper compression should be around 160 psi, with this, it is real that I have a compression problem, since it has new gaskets, it leads me to think that it may have an internal problem, the rings may be? I will need to evaluate this, it could be cheaper to replace the engine instead of repair it..

    Engine compression

    Today I pulled codes from the ECU (I got an scanner), I got the next codes: Code 111, KOEO ==> System Pass Code 10 ==> This is not in the manual code 176, Continuous ==> Failrue into the HEGO (HO2S) sensor fault / allways lean. I didn't executed the KOER test since the user's maual says to not execute it until all previous codes are repaired. What is the HO2S sensor? the Oxigen sensor?

    V6 stalling under load

    Well, P1744 is the torque converter lockup circuit. Could be wiring, could be a solenoid in the transmission. I'm sure the shop will test the circuit and see if it's properly working. -Dominic

    V6 stalling under load

    Got it back from the shop today. The mechanic said the FRP sensor works properly and the fuel pressure is correct. The mechanic says P0193 is no longer coming on. Code P1744 is now coming on. All through all this the OD off light blinks after driving about 10 minutes. The car is now in the transmission shop. Any thoughts?

    V6 stalling under load

    Yes, the CEL comes back on after resetting the PCM. It's still in the shop and the mechanic also said he wanted to drive the Contour for a few days.

    V6 stalling under load

    Is the CEL still on with the P0193 code? If so, they are overlooking something. -Dom

    V6 stalling under load

    Car is in the shop now. No sensors were found to be bad. Thoughts??

    V6 stalling under load

    That's good to hear. Sounds like you still need to have that FRP sensor looked at though. -Dom

    V6 stalling under load

    August 25 replaced PCV hose that had a large crack and leaking vacuum. The stalling stop. Still getting a code P0193. The car is running fine now.

    ABS false pump actuation

    I disabled mine as I thought it worked way too early and too easy, the car would not stop in nearly so short a time as either of my two Focus cars which do not have it. I myself when needed am pretty good at steering out of a slide that takes the car sideways so that helps.
  17. Tires can easily do it if close to dead. The outer tie rods being loose can do it as well.

    Engine compression

    The numbers given if real are lousy, need at least 150 psi with that engine, but always suspect the gauge as they give countless problems. 100 psi if real is a virtually dead cylinder, it WILL try to miss at that low, the number is low enough the heat drops off that cylinder and then the plug will not burn off to stay clean to fire right.

    Engine compression

    Yes, it runs good when hot but with poor milleage, it used to provide 300kms per 3/4 tank, today, they are 220kms per the same 3/4 of tank, both measured in city trafic. The plugs and cables are new, they have at most 1000kms, the previous ones that were older provided me a little less milleage and less power at runing. I will have to talk, with the guy in the service... as I see it, in the mid to long term, it could be cheaper to replace the engine with a used (with warranty) but newer Mondeo engine.

    Engine compression

    While we're on the subject, the early 2.5L's had some issues with carbon tracking the plugs. This led to them stuttering and running poorly cold or hot. You said it runs fine when hot, but gets poor mileage? Intake gaskets leak, fuel pressure regulators fail... It could be a lot of things causing those issues. -Dominic

    Engine compression

    Hello, No, I hadn't scanned it yet, I will take it to the service next month for emission testing, I'll ask them to scan it, anyway, the Check Engine light is off. Vacum leak, I doubt it since it hasn't been run much since the engine was resurfaced, but still a possibility. What kind of problems can the injection system could present?

    V6 stalling under load

    High input normally refers to electrical voltage received from the sensor to the PCM, not fuel pressure. Plus, if you had high fuel pressure you wouldn't have lean codes. Everything would be the exact opposite. -Dom

    V6 stalling under load

    Thank you. I plan on putting the Contour in the shop next week where they have all the equipment to check fuel pressures. Might it also be a defective fuel pump/filter? The reason I ask is regarding the FRP code which is 'high input'. Does 'high input' mean to much fuel pressure?
  24. BuckeyeSVT

    V6 stalling under load

    Well, lets look at the codes. P0193 is the Fuel Rail Pressure Sensor stating high input. This normally occurs from a wiring short, or the sensor itself has failed. P0171 & P0174 are system lean codes for both banks. If your FRP sensor is malfunctioning I would suggest repairing that first before getting into the lean codes as they can relate to eachother. Without a proper scan tool, you won't be able to see what pressure the FRP sensor is telling the computer the fuel rail is at. The sensor is around $60 last time I checked, but I don't advocate throwing parts at it. Do you have anyone with a professional scan tool that can look at the data from the sensor? I don't like spending other people's money -Dom

    V6 stalling under load

    Ford Contour 1999 2.5 L V6 (24 valve). 105,000 miles. Auto Trans. August 8 engine runs very quiet. On August 10 engine started stalling under load but kept on running. Set off 1 check engine codes. The OD Off light began blinking. Exhaust pipe blew off and engine began running fine but loud. Muffler shop repaired the exhaust leak. Car ran quiet and did not stall. The Codes were: P0193 On August 13, 2018 while warming the car up in park the engine began speeding up and slowing down. It sounded like the computer was recalculating the fuel/air mixture. When the computer was done and we began driving it started stalling again. The ‘check engine’ light came on again with 3 codes. After the car completely warmed up it ran quiet and did not stall. The Codes were: P0171 P0193 P0174

    Engine compression

    My guess is a bad sensor, vacuum leak, or other fuel injection system problem rather than low compression causing most of your problems. Have you looked at OBD codes if any? Does anyone have a diagnostic scanner that is compatible with your car?
  27. Comano

    Engine compression

    Hello, Thank you for your information, I see that the issue is not as big as I initially thought. The engine runs "good" in load, but sometimes is a little rough when in idle and around 550-600 rpms, after a few seconds it changes and stabilizes around 750 rpm. The cylinders were machined about three years ago, the cylinders were adjusted to 0.20, I see then that I need to check with the guy that did the job to check the failing one. In the time this happens, does this justifies lack of power when cold and bad milleage? By now, the car is used about 7 to 10 days a month.

    Engine compression

    Somehow I misread 100 as 110, so yes there is some difference there. BUT - I'm not convinced that the other numbers are low. Since the intake valve stays open during the first part of the compression stroke, you will never see as much pressure during slow speed cranking as you'd expect from the compression ratio. Taking Buckeye's number of 120+ at lowish altitude, 115 at your altitude sounds very reasonable. Altitude calculator online says that your air density is only 77% of sea level which should cause a 23% reduction in the compression reading vs sea level. If you can find a "leakdown tester" that may give some indication, in addition to numeric values it is helpful to just listen to where the air is going on TDC of the low cylinder vs TDC of a good one. Crankcase (oil filler cap) = rings, exhaust pipe = exhaust valve, throttle body = intake valve. If the engine has not been run recently, all these things are iffy as a tiny bit of carbon or corrosion can cause a biggish leak.
