jerking and stahling
When my car is first ran (cold start) it runs great for the first few minutes then starting jerking/bucking and then at a stop will stahl. I have taken it to three shops that can't seem to fix the problem or find out what it is. I replaced all of the hoses, fuel regulator, spark plugs and fuel filter. No change. The jerking also seems worse when I am stepping on the gas. What could be the problem??? One shop did say possible pcm (something computer module).....
