So here is the issue I keep getting a cel which im blanking on the code but its rich bank 1. I will get the code tomorrow. The car is a vortech sc ap1 and I have just replaced the upstream o2. So I know that code could be a number of different things but I have two other issues that lead me to think it might be a TPS issue. It seems like at a certain rpm and certain throttle percentage my car bogs out and runs full lean but not every time sometimes it does it often sometimes it doesnt do it at all. Its partial throttle I am guessing around 10% and lower rpms crusing at about 2200 rpms. Also I have noticed when the scan tool is hooked up I dont have full range of the tps it goes something like 12% to 77% or something along those lines. I have no idle issues no problems stalling just that strange bogging issue. So where should I look is the tps a good start or am I barking up the wrong tree? Thanks
