the TPS is fine, I have an EGR but it is shut off with the chip in, even with the chip out it seems to make no difference with the vacuum lines connected or disconnected, I havent tried to pull any codes yet, I am going to try a new mass-air meter next weekend, I have a 94 maf electronics I can use on my `90 C&L with a 30lb sample tube, I just posted to see if they are the same. If I got a scanner and pulled the codes would one even show up without the check engine light on?
