My 22re efi swap was good for about a week, then my tps went bad and it ran like garbage. swapped on a new throttle body so i wouldn't have to adjust the tps and it runs great, but at idle it jumps up and down from like 1000-1400 quite quickly...

will adjusting my TPS fix this? i've never adjusted one before, but i have instructions on how to.
If not, what will?

Thanks,
Ryan

I had the same engine and had a TPS go bad on the trail; I had no power and the truck was basically undriveable. To get home, I just unplugged it and everything ran fine, other than a slightly higher idle. So you may be able to use this info to determine if the problem is your TPS.

if the idle was set to high on the replacement throttle body then the computer will try and bring the idle down by shutting off the injectors and then turning them back on again when the idle is lower, thus giving you a surging idle. to check if this is what is causing your surge just back the idle screw off a bit to see if the idle smooths out. a vacuum leak could cause this concern as well.

Thanks,
I'll give those a go and see what happens.

Basically, the wire on the first throttle body came off while i was on the freeway so im thinking it shorted then... the idle would drop really low and almost stall, then come back up to regular idle...

This one seems to be running great aside from the up and down thing.

Yotas have an iacv anywhere on them like hondas do? It'll give you the same symptoms when it goes bad or even if you have an air pocket in your cooling system.

Does the 22re have a coolant line through the TB like the 3vze? If so perhaps there is some air pockets in the cooling system. If not, make sure the idle is adjusted to stock (around 750rpm) or it will surge when you're on the brakes.

And defiantly test/adjust the tps, who knows if the used one is in spec or not? If the tps is the problem, unplugging it should stop the problems (but give you a high idle IIRC). If that works then you found your prob

:withstupid:

mine surged when the coolant level dropped too low... check your coolant level as well as for any air pockets, and be sure that sensor is functioning properly

Thanks guys it's fixed. was a mixture of the idle too high/ tps out of adjustment slightly. the coolant sensor thing also seemed like a good option as it happened to my cousins runner...

Good, so time to get wheelin Ryan! Also , you'll have to show me how to adjust the tps, i'm not sure mine's to spec either.
