Question:
Cylinders 3 and 5 had low compression. A head gasket didn't fix it. Turns out the head had previously been resurfaced and the pushrods were too long. They were holding the valves slightly open at all times. I put some shims under the rockers for a quick fix, and now have 170 - 180 PSI in all cylinders, but it still idles rough and hesitates (badly) from a stop.
My fuel door on my car won't close (seems ajar) - how can I close without body shop repair?
o2 sensor hops around 350mV or so (seems a bit lean). The TPS output voltage looks nice and smooth, and is 0.46V at idle (low?). When it stumbles, O2 sensor output pulls to 0, so it's a lean condition.
I'm guessing either MAF sensor, clogged injectors, or low fuel pressure. Fuel pump seems to pressurize system very quickly, but could be a clogged filter, I don't have a fuel pressure guage to know for sure.
Im lookin for a website that does custom interiors for cars?
Anyone seen this before? I've heard rumors of faulty ECMs in these cars. I've done all the diagnosis I can, now I'm grasping straws... Help!
Answers:
How are your plugs and plug wires?, How is the timing chain?
Sometimes you can have a plug or two misfiring.Can be caused by just being faulty or cracks in the enamel shield and jumping spark.Make sure that the plugs are in good shape and the gap is right.Plugwires vcan be checked for resistance.Use a timing light to check for timing.If the timing mark on the Harmonic Balancer seems to be jumping around.Replace the timing chain.The chain may have slack in it from wear and tear.The stumbling seems to be electrical and not a fuel condition.
When ever I make a wide turn, my car makes this winding noise. Does anyone know what this might be?
If you ran that engine with out of spec. parts, then the damage is done. A complete overhaul by a mechanic who knows what he is doing is probably the only way to save that engine.One thing that I saw several times was a dirty mass air flow sensor.
Disconnect it and drive the car.
If the problem goes away.bingo.
How long does it take your car to cool down so you can put coolant in it?
I can tell you it is not your ecm. A faulty ecm in this vehicle will cause it to stop/die when first started. And that would go on for about 5-10 minutes each time you start the vehicle.Whats the best $600 I can spend on gettng the most performance?
Probably your injectors, quite possibly could be a filthy fuel filter.
