ok i got a few questions for ya

well if got a SAFCII set up in my 87TII right now and it can read the TPS voltage, ive just been noticin in the past couple days here how shitty my cars been running, i havent touched the SAFC everything is set at 0's, my idle is all over the map.. mornings its reving up to 2grand and stayin there while driving and after being warmed up for like 15-20min unless i sit and let it idle at 2grand for around 5min then it drops to 800-750.

2min ago i went to reset the TPS to 1volt like it should be , got home cars warm and tps voltage was around 1.2 then i pull into my garage turn off the engine its at around 1 volt perfect, so i start it back up again for like 1min turn it off now the voltage is .985 and my idle is no more she keeps dyin.

im thinking first off i got a Vac leak somewhere
or my TPS is messed

next on the list
im gettin some bad hesitation at around 2.5-3 grand unless i kinda push down the gas and release, its like while my turbo spools up it slows my engine down? but its worse when im just cruisin on the highway in 5th and kinda just let it sit around 2.5-3k its like the injectors arnt kickin in for some reason, when i release the car kinda jumps foward like the engine is relieved. so..... im thinkin maybe my injectors are fucked and pumpin to much gas in? or due to a Vac leak im gettin hesitation.

If you could give me any info help on this it would be greatly apreciated

Slim,

I have the same problem with the hesitation around 2.5-3rpm. I'm not sure if the injectors are loading up or wat. wat have you upgraded on your car?? Do you have bigger injectors?? I just installed a street-port 13b in my 89 t2. I have a t3/t4 hybrid turbo with front mount int. i have the factory primaries and 750cc secondaries. Right now i am working on getting a ecu for my car so i have not tried to fix the hesitation problem. I am hoping the ecu will fix that issue. I am still breaking in my motor so right now i am not going to do anything else untill i get an ecu. That is why i am curious on wat u have done with ur t2.

im got stock injectors, stock turbo/intercooler, FCD, walbro fuel pump, Full 3"exhaust, downpipe, 3" TID, and this was happening before the SAFC was installed also , not the hesitation tho or maybe just not as noticeable. and when my car is cold TPS reads 1.4V. need any help
