Ok, upon start up, this is after $500 bucks at the mechanic, the engine "putts" until I give it high rpms with gas. Then it seems to idle ok but only in park and neutral. Once in gear, back to the putting. Quite rough. Air/gas ratio is good and when idleing in park, rpms check out good. I think what I am getting at is I have no cold start high idle, where the car starts at high idle until warm and then goes to a low idle. Everytime, I start it up and it'll put until I give it some gas for a few seconds. Whether it's warm or cold, it putts. Any suggestions?
