Check fuel pressure and ignition, the best thing would be to check it with the scanner

Sounds like you lost O2 ControlCheck fuel trim & data with professional scanner & suchYou done as far as working at home, you did allyou canYou have a rich condition (CO)Seems as though the coolant sensor is not working &your in open loop

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: diyobd2.fr

what type of car would really help and engine size

check for play in gear box and the dampner in steering shaft

Go to autozone website they have wiring diagram available online

possibly a faulty injector for the miss but if you have a head/headgasket problem it would account for the exhaust. Do a compression test and radiator pressure test to eliminate that area of concern

Looks like all four wires go from the IAC to the computer.

There must be a pressure relief valve block or breather valve has to be high oil pressure and it is venting through your dipstick. Lagging out could be blocked injector, worn spark plugs or other fuel starving.

The car should be on jack stands. After disconnecting everything from the transmission, put a jack underneath it and lower it while moving it towards the rear of the car. If this doesn't work, hit it a bunch with a sledge hammer. Good luck-----------------------------------------------------------------------------------------opcom 2010
