Next, what all others said - go back to the stock chip, make sure fuel supply isn't starving (even though that would not recover as it does in your case) and then check the AFM.
Your AFM could have a "flat spot" damage to the wiper trace that momentarily tells the DME to lean out at a particular air flow rate. A simple test with a 9V block battery and a DVM can tell if it is working properly. You have to take the AFM out but don't have to take the top off. See here: Air Flow Meter (AFM) Operation and Testing |
I will have to check this out. This seems like a likely suspect. The article indicates that there are 2 different versions of the AFM, could there be a possible mismatch between the AFM and the replacement DME that was installed?
Also, how do I remove the AFM?
Thanks!
