5SFE - CT-26 Turbo with HKS Turbo Timer and HKS Super AFR Air/Fuel management system.
Other than Weak Idle my car...
Stuters, shunts, floods itself, etc. typically in low gears, at low RPMs. If I keep RPMs between 3k-4k I can normally pop it out of First and Second gear. If I let it down to low RPMs while getting outta first and second gear, it almost seems as its gonna stall itself, but never has, just a violent back and forth chug untill I rev upto high RPM (if it does come out...sometimes I'll have the clutch all the way in with the gas DOWN for 10-15sec and no change...just chug chug chug).
At first I thought it might be a vacuum issues, and replaced the MAP sensor, and checked out vacuum lines. Problem still exsists.
The reason I think its a Air/Fuel mixture problem, is because I followed this guide:http://www.6gc.net/index.php?action=howto&itu=33
After resetting my computer's Air/Fuel mixture IT RUNS PERFECTLY FINE, for about 12-18 hours. And then goes back to its origional problem.
Does this limit my problems to tuning my HKS AFR on a Dyno? It was installed in California, and I live in Arizona, so I know I should get it tuned anyway. But should that controller alone cause such a bad problem?
Any help would be appricated.
