You say 'it's tuned for the new injectors', but it'll be rich at idle with many performance cams until you pull some fuel in lower rpms. I had that issue with my 94 when I went to a 292 XFI cam.

I suspect you mean "injector constant was changed to accomodate injectors" not that you actually had a dyno tune with wideband done. THAT is what you need... and be aware that if it IS rich down low, you'll wash the rings down in VERY short order... perhaps the performance shop can dyno tune it for you.

 

If i remember right the antifreeze was at the very bottom of the oil pan and i was able to just loosen the bolt enough that only a small amout came out and it was mostly coolant so you can try this to see later if it all gone of needs more flushing. I bought the $5 Walmart oil and just drained the filter so it was pretty cheap to do it.

 

I didn't know there was a difference, I just have a new pcm tuned by madz28 for all the new mods I made. But the shop does have a dynojet, so we'll have to see what they say.

 

For a dead on tune, of course a dyno is the way to go. If you gave Ion your exact combo though, I'm sure he sent you a tune that is very close to where you won't be washing down your cylinder walls with gasoline.
