[QUOTE="agent-orange, post: 16442404, member: 124824"] Hi guys I have an eaton swapped 2001 cobra, I did a eaton swap several years ago and I never had big problems so far. I have several "problems" with my Cobra, which are annoying me. I replaced the clutch and flywheel 2 years ago and since then I had the problem, that the car has a very high idle. I thought it's because I installed an aluminium lightweight flywheel so I never cared really about it. But always when I press the clutch while I'm driving, the idle goes up to around 1800-1900rpm for about 20-30seconds and then comes slowly down. Is that normal? I dont have any shifting problems or so. Just when I press the clutch, the RPM goes up and comes down as soon as I shift or wait long enough The other problem is when I start the engine, the RPMs are also around 1800-2000 for about 1min and then goes down to around 1100-1200rpm. The engine is also quite shacking, when its idling at 1100-1200rpm. I recently read, that the idle of the car should be around 700-900rpm :( So I connected my SCT and read the DTC codes, it shows me P0135 & P0155 which should be the upstreams O2-sensors. I already checked the fuse, it's OK. So I ordered new O2-sensors, but didnt receive them so far. I also ordered a new MAF, cause I'm using still the 01 stock MAF. I also checked the IAC, but when I disconnect the IAC shuts off immediately. So I guess the IAC is working, specially cause I dont see any other error codes. Is it possible that the O2-sensors cause all this problems, that I have? A vacuum leak would produce other error codes or? Another thing is, that when I shut the engine off, I hear a strange whistling sound from engine for about 20-30sec. I dont know if that is normal. I uploaded 2 videos on youtube: High idle: [MEDIA=youtube]aw_GqYTBv5Q[/MEDIA] Whistling sound: [MEDIA=youtube]GnZ6Aqj_Vqc[/MEDIA] I'm thankful for any help [/QUOTE]
