Low Rough Idle
Had a couple problems lately with the Mach and wanted to get some peoples insight into what might be wrong. Car started idleing really low with AC on and would even stall out at red lights and such over the summer. When the AC was off the car seemed fine. I had installed the IAC restictor plate before the summer.
Recently the car started idleing rough and stalling without the AC on. I replaced the Alternator last week but no change. I removed the IAC restrictor plate and it still stalls. I just ordered a new IAC and im going to try that. Any other things to check? Maybe a new battery or fuel issue? The car is only idleing at like 400 rpms and surges slightly. I notice a drop in rpms when i press the brakes. Have to give it some throttle to start up also. Thanks. |
