Guest Anonymous Posted January 22, 2001 Share Posted January 22, 2001 Car idles fine but when I step on the gas at about 2000 rpm the it bogs down drops back to idle. When cold for the first few minutes car runs ok but then it has no power in any gear. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted January 30, 2001 Share Posted January 30, 2001 have you checked your timing and if that's fine try a different AFM, lots of basic tuneup info at www.zhome.com Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted January 31, 2001 Share Posted January 31, 2001 Is this the factory 6 or a V8? Only does it after its warmed up & after you push it to 2k rpm's? Does it after a cold start, warm start? Quote Link to comment Share on other sites More sharing options...
Guest Jason Posted February 2, 2001 Share Posted February 2, 2001 My 82' bogs when cold, but runs fine after a min. I always felt it was acceptable for ancient FI technology. Maybe try blocking off the exhaust gas return? The EGR valve is supposed to be closed both when the engine is cold, or past a certain throttle point. If it wasn't closing when it should, you would lose some power. Quote Link to comment Share on other sites More sharing options...
