i have a trick flow intake manifold and ever since i put it on when im down shifting and i come to stop at a light it idles at 2000 rpms or higher like 2500. but at other times it will idle normally about 650 700. any ideas as to wut is causing the bouncy idle>? ive replaced the tps sensor 3 times and at first it seems it help but then goes back to doing it again

I have a 93 and just installed a track heat with 1" spacer, it idles 800 to 1000. Did you replace all of your vacuum hoses with new ones? <edited><editID>Sean</editID><editDate>37843.9903472222</editDate></edited>

check your voltage on your tps. it should read between .94 and 1.05

I think buzz might have hit it...but you want it .94-.99
make sure there is no vacuum leaks...retighten all bolts
