well i just got my new scondaries put in and my t2 was running like a champ and than like 4 hours later the car wont even idle and it is back firing like crazy when i try to keep it goin. now a couple days later its startin to do it again randomly. and the only way to get it started when it does this is to hold the throttle wide open. but once u get it goin i have found that if u redline it thro a couple of gears it is back to normal. its really weird cause before i put the secondaries in it never did this. i think that they might be sticking open letting way to much fuel in. could this be correct? thanks for any help

does anyone know what could be happening here?

does anyone think it could be my tps? it only happens when i am cruzin at lower rpm's.

could very well be the TPS...worth a try adjusting it.



when the TPS went bad on my T2 it would studder, hesitate, backfire, not rev past 4K. I checked the codes and sure enough it gave one for the TPS. Threw a new one in...adjusted it slightly, and its been fine ever since https://www.nopistons.com/forums/pub...IR#>/smile.png
