heckler Posted March 16, 2013 Share Posted March 16, 2013 I found that really hard to read! - but I'd look at ICV as mentioned. Quote Link to comment Share on other sites More sharing options...

johnny g Posted March 16, 2013 Share Posted March 16, 2013 Through translate.google.com Hi Guys I need some help. My Supra N/A was driving fine, it's had a service, and new rocker cover, and gaskets. It was fine, but has a problem now when I am driving, or at a junction. The car normally revs at around 100 rpm, but it keeps droping to around 200rpm with no warning. Diffrent types of driving affect it, the revs just drop when they want. After they have dropped, I have tried bliping throttle. It doesnt make any difference. I can pull away and drive and sometimes it goes back to normal straight away. Other times it can take miles and miles. My exhaust manifold is blowing, would that affect it? But as I said, this idling problem is not a daily thing, but does happen a lot. Any ideas please? I need my car bact to normal ASAP Quote Link to comment Share on other sites More sharing options...

Nic Posted March 16, 2013 Share Posted March 16, 2013 If the exhaust manifold is blowing it could be effecting the signal from the O2 sensors causing the engine to run rich. Quote Link to comment Share on other sites More sharing options...
