most common mistake: when to read the plugs.Teggyman on Feb/15/04 said:you are running way too lean. I bought an AEM fuel presure regulator and it helped out a lot. I got that tan/brownish color which is closest to 14:1. Do you have a custom intake installed?
Ray: you may want to take your car to a dyno that has a wideband O2 sensor that they can place in your exhaust tip. Do 3 runs after your car has been warmed up. Get the torque curve and the continuous air:fuel ratio vs. rpm graph. Tell me what you get.Teggyman on Feb/15/04 said:I don't have excess carbon deposits on/around my muffler tip at all. I also have advanced ignition.
It's not a real issue with plugs, just use anti-sieze every time you replace them to be sure.StyleTEG on Feb/16/04 said:Is there any concern about pulling the plugs while the engine is still hot?
Seems every once in a while there is someone who says that pulling the plugs while the engine is still hot, has a greater chance of stripping or "pulling" the threads out of the head. (while this may be an old auto myth).
Would there be any disadvantage to letting the car cool down completely? (provided you killed the engine right at a WOT run)
