need some help here guys... i got on the boost a little bit in my 87 T2 on the way home from work today, and when i got off the interstate, i pushed in the clutch, and my rpms stayed around 4 grand. i reset my tps last night and was idling right under 800 rpms, now today when i get on the boost, i push in the clutch and the throttle wont go down. its like the throttle cable is stuck, but its not. i checked it. do i need to reset my tps AGAIN!?!?

 

TPS won't do that. Are you SURE something isn't stuck?

 

yeah nothing is stuck bro. i have low oil in my car, could that have anything to do with it?

 

No. This is really weird. How often does it do this? What happens when you start the car now? Does it immediatly jump to 5k, or does it only do this when in boost?

 

when i start it, it immediately climbs and stays around 5k

 

i was thinking that maybe my secondaries could be stuck on... but i wouldnt think that that could make my car's idle multiply itsself by 5 fold

 

there are no rotary shops around here and the only place to take my car is the mazda dealer... spending money for them to just look at it is not what i want to do.

 

It's probably just a throttle body problem. You don't need a rotary mechanic for that.

 

hey, question NZ... can i take the upper throttle body off without replacing any gaskets when i put it back on?

 

You mean the upper manifold? It might be possible, but if it's never been off it's probably baked solid and will be damaged when you pull it off. It's only a few bucks anyway so why risk a vac leak?

 

hey rico, the tps was set at 4.6 kOhms..... we set it back down to 1.00 and it solved the problem.
