the other day i took my jeep out and got some degreaser out and proceeded to degrease the motor to do a new valve cover gasket and i sprayed the whole motor down with the hose after doing so the truck was hard starting and then ran good but idles at 1500 rpm and the transmission control module is not working and no fuses blown i need help here i hooked up the scanner and it said tps and bus something with tcm.

 

Year? TPSs hate water.

 

its a 1997. could that be the why its all not working? the tps?

 

Yep. They don't like water sprayed on them.

 

i just posted about this the other day, jeeps hate water. mine was idleing round 2k, i unplugged the tps and iac and cleaned them and there conections with carb cleaner. let it sit for another half an hour and everything was back to normal

 

Well why would my tranny control module not work i have no lock up tc and it doesnt down shift and sputters alot now

 

the tps sensor has 2 plugs, 1 controls the motor the other controls the trans.


you might have fried your tps they do not respond well to water...

 

This^^. Why don't you try this although I don't have high hopes for it. Unplug the 2 connectors on the TPS as suggested in another post. Spray them out with electronics cleaner and plug them back in.

Chances are your TPS is toast.

 

2x now it has rained..I think my jeep hates water after it was sunk in the river by the PO..
My jeep misfired or something..like crazy, rpms fell to 0 and even if I floored it the rpms wouldn't raise/rev..cat glowing red..let it site for 24hrs and its back to normal?
Did it last night as well..somethings getting wet and its reaking havic when it does..idk what it could be though?

Something gets wet and the jeep feels like its misfiring..it won't rev up at that point at all, doesn't matter how far the pedal is pushed. It starts fine but sounds horrible..sounds like its only firing on a few cylenders when it happens honestly. Cat glows red..idk! Dries out and I'm good to go!

 

wait for it to dry out. Then once it's running fine again, take a spray bottle with water, and start squirting things...

 

it could also be your distributor cap got water in it, i had it happen with a 86 ramcharger, only hit on a few cylinders. take it off, spray it out with WD 40 and wipe it out. may fix it, may not, but i have had it happen so it could be that.

 

ok so today im gona go get a new tps and see what happens if that dont fix my tranny control module should i go get a new one of those also?
