ok i finally drove my car tonight...
so far it stalled twice once while off throttle cruising coming to a stop, an the second time it started to run rough then just shutdown? no codes on scanmaster
ok now figure i better get close to home so on the way home i step into it an it almost stalls, hmmm
ok home in driveway rev it up a bit an its like theres a flat spot in the throttle if that makes sense? starts to rev then nothing almost like when you have a 4 bbl carb an the secondaries open too soon...
the only thing ive changed is the 4inch maf pipe the translator an the 3.5 maf meter ..
ideas lets have em boys.... before the snow comes lol
-
Check the dip switches on the translator and make sure they are set for your MAF. Instructions are on the underside of the lid for the translator box
-
If you changed to a 3.5" from a 3" did you rotate the knob to tell the Translator you swapped MAF's?
Normally when my car has a tip in stumble it's because the throttle blade is too closed and the IAC is doing all the work. Cracking the throttle increases the airflow too much too fast and it's like the accelerator pump on your Holley is leaking badly.
I like the have my throttle blade open almost the whole amount I can get away with. That way the IAC only has to kick in very little air to maintain ECM control
-
well I still have it the switches I have are set for the 3.5 maf an o on the fuel
could I try the 85 mm settings? I mean 85mm is pretty close to 3.5 inches?\

Did you reset the pcm after making the changes?
