my 01cc rt has a interminant bake fire The truck is " Falling on it's face " it sounds like someone hits the block w/ asledge hammer when this happens
occus under normal accell and ca happen when reved from idol NO codes and very hard to dup problem once it occures seemes to happen around the time the motor warms up and leans out but this has happend after running for more than an hour

it does not hapen often but when it does it's quite embarocing Please if u can help any advice is much apreciated????!!!!!!!!

 

have you checked the most obvious? The map sensor, maf sensor, 02 sensors or tps sensor? the most common sensors related to fuel delivery problems. The crankshaft position sensor would screw up your timing, but all of these should come with a trouble code.... got any?
