TPS/MAF/IAC and the CEL that wont go away

[Josh62]

ap1000, I feel your pain. I've been fighting mine for a few months now. Its hard to drive in Atlanta traffic when your truck hardly idles! The cel just came on yesterday with p1121. I've already replaced the IAC and fuel filter, cleaned the MAF and throttle body, tuned it and crawled all over looking for vacuum leaks. I guess I'll try the TPS tomorrow. I really hope it works. Thanks for the help.
