My mechanic accidently made the car back fire into the manifold when reving the motor to check to see if the belts had quit sqealing after replacement. Since then it won't start when it's hot. They've had me replace the cap & rotor which didn't have any black or cracks in it, found a small vaccumme hose on the left side that was under the MAF sensor.
When it's cool in the morning its fine but by mid afternoon it won't start hardly, it will cough, shudder, back fire a little and die. I've found it will eventually start if I keep pumping the pedal like I do on my old farm truck and it will fire up and blow smoke out the back that has a strong gas odor to it. Once it's started it runs fine, idles fine it's just restarting it I go through the same process. What should I look at doing next? The VCM is giving fuel fail 13 for the MAP sensor and on this car it's apparently 2000$ as it's attached to the ECU for the entire injection system made just that way for just that car just that year. I'm trying to find another solution before plunking down that kind of cash on it and finding out that it was something else.
Thank you in advance!
have the same problem?
