While driving down the road and accelerate car almost dies. If I let off the throttle it goes away for a short time. At the next stop it dies but starts right up. I've checked for code and there are none. I've replaced the EGR tps coils ignition module IAC fuel pump fuel filterfuel pressure is 38-45psi. I've used a scanner and drove down the road and everthing looks normal. Any ideas? This doesn,t always happen but happening more and more.

Hey You probably have this fixed by now but i just wanted to say I had the exact problem with my lumina and it turned out to be a bare wire to the crank position sensor. It was intermitent as heck but we finally figured it out.Replaced a section of wire and it fixed it.

Hope that helps.
