Hello. I bought this site unseen with 87k on it. It was only running with foot on gas. If I let it idle it dies when it hits 400rpm which happens immediately. I started off by replacing IAC controller. That did nothing. Then I tried cleaning MAF sensor, nothing. Then I drove it by a mechanic and he pulled the plug on the maf sensor. When he did that it idled without dying. He said I should start by replacing that. I did. And it still dies immediately. Any ideas? Thx. He said I should just change all the coils and plugs and it should be fine. He said the engine sounds and smells great when it has some gas. He doesn't think it's anything serious. He didn't seem to want the job. Told me to do it myself. I guess I'm thinking it's something more. Vacuum leak? Fuel pumps? Injectors? Idk. I'm trying to get this done cheap. lol
