ok, here is the situation. My car is running rich about 14.1 :1 to be exact. i was throwing a p0100 code but I replaced my GMS MAF with the stock MAF and I am still running rich.. so... I can put it in neuatral and rev it all the way up with no stumbles or misses... but when I am on the roas and I get on it, once it hits about 4k it misses and stumblws REALLY bad. I have an autotap, so what should I look at to try and diagnose this problem?
Thanks alot, Tony

 

Export the tables into this post.

 

which tables?

 

Stumbles under load are often the plug wires. When is the last time you did plugs/wires?

 

I had a problem like this once and I replaced the ign. coil and it fixed the problem, may not be the same but it wouldn't hurt to check. (MSD) !

 

The tables from the autotap. Export the file of say a 30-80mph drive under load.
