no No, NO!!![/align][/align]Themixture goes "rich" (a tiny bit richer than it would be otherwise) for the very brief period of time that the engine is decelerating, and also it's "rich" for a closed throttle condition meaning that there's only a very small amout of fuel being injected anyway--there is no way itcan measurablyeffect gas mileage, or is "bad" for the car. [/align][/align]When the engine is operating at normal speeds and loads the IAC is closed and having it blocked as tight as a pig's butt would have not effect on anything--as I said earlier, I get 22.5 to 24 mpg (all highway is the best) with this mod and 3.73 gears...[/align][/align]You people that don't have a clue as to how the EFI system works need to keep your yaps shut and stop spreading FUD (Fear, Uncertainty, and Doubt)...[/align]

I copied the old copper plug mod...used a Dorman freeze plug..drilled a small hole(dont remeber what I started with) and enlargedto where it didnt stall..and the idle came down to my liking.Easier IMO than tracing a gasket,cutting out holes ,Removing IAC and re-installing,.....
Dorman part no. 555-015......75 cents..

Custom Tune, decay rate adjustment, no worries! A tune is worth it... It fixes most problems AND you learn where your really at in hp/tq. This is one of the best threads I've read in a long time though.
