MAF, PSM, ABS issues!

Recommended Posts

I know this issue gets beat to death but but I cannot seem to resolve my issue with over a year of dealing with it!!! Last year I converted my car to rear wheel drive. After that I would get the dreaded PSM/ABS failure whenever I would get a little spirited in my driving. Track days were the worst obviously. So I would disconnect the PSM pump in the front trunk. This would at least allow the ABS to continue to work. At first I thought this issue was a result of removing the front running gear and thought the ECU needed reflashing since the error said something like "Signal improbable".  


After a few weeks, it started throwing the P0102 code, so last March I replaced the MAF. I thought this had fixed the PSM/ABS Failure issue, but upon the next track day, it reappeared. 


So now I got the car back after 6 months of front end conversion and it will barely run with the MAF connected. I have been disconnecting the MAF to drive the car, and it runs great, but the PSM/ABS Failure and P0102 occur instantly. 


So I got a Durametric tool and connected it and have attached a sample log. The MAF seems to be working based on what I have read online, but it runs terribly. It spits, sputters, and searches for an idle speed. When revved, it is not smooth, and won't hold a steady RPM. Disconnect the MAF and it runs fine, but the PSM and ABS shut down and the CEL comes on.
