210 849 4397..

I would be willing to bet that you might be dealing with that fuel quality switch on the rear of the ecu.. I have played with it alot latley and found what seems to work for me and my car.. but you never know how mike might have set it up.. ill be in austin tomorrow morning from like 10 -2 and thought we might be able to hool up for lunch of sometihing like that
I just got a new AFM...well remanufactured...and I still have the crappy rich running around idle but now I also have detonation and hesitation in the middle of the rpm range under medium to high engine loads. Crap!

Detonation is not good.

I went over my engine with a propane torch (unlit, of course) for like 20 minutes looking for vacuum leaks. I didn't find any.

I think I need to get a lamda gauge. Then I need to figure out WTF is going on.


I have been having some detonation and hessiation from my car in the last few days.. I have done alot of playing with the overall fuel ratio via the ecu but I dont know how to check to see if its all calabrated correctly under the hood? I checked the intake blocks and they seem ok.. so I am not sure what might be the deal.. I might have some fouled plugs or something like that but any help on adjusting air to fuel ratio would be awsome! Ahh and maybe some info on how to verify the .o2 is working?
