[karan]

Family,

So i didnt go to work today since my jeep was sick :)
error codes didnt reveal anything.
so i went ahead and bought a new TPS, just finished installing.
check engine light went off, no hiccups :)
its snowing here n i live in downtown calgary so couldnt drive fast, but upto 35 m/h and fast acceleration showed
no hiccups or any thing like that, jeep ran well.
I thank you all from the bottom of my heart to come and help me in the hour of need.

You might disconnect the plug and reconnect it.

Thanks Bounty Hunter, i followed the steps and all that gets displayed doing your steps is
2.5
after displaying 2.5 nothing else is displayed, i waited and tried the same procedure many times but always 2.5 is displayed.
what would that mean?

Code 25-Automatic Idle Speed (AIS) motor driver circuit-short or open detected in 1 or more of the AIS control circuits.

BH,
thanks for the code help.

Family,
Although the jeep runs fine after changing the TPS, no hiccups, but i did notice some thing when i opened everything up today to replace the faulty TPS.
I noticed engine oil on the walls of new throttle body spacer, it wasnt dripping or anything but yes oil was there and i could touch and see the oil on my fingers.
Important to mention i had only driven the jeep for close to 30 kms yesterday after installing the throttle body and throttle body spacer.
jeep was parked for more than 17 hours before i opened and saw the oil there.

is it fine or do i need to do something??


P.S. check engine light is off now after changing the TPS, which is good.

I'd wipe it off and keep an eye on it, doesn't sound serious.

Thanks BH, do you think the gasket could be causing it, i had one new gasket that i used between TB and TB spacer and i reused the old gasket between TB spacer and the
Intake. that wasnt torn but wasnt in the best condition either. could the worn out old gasket cause any issues??

your idle would be high if there was a leak at the t/b gasket

Idle is actually fine, just at 800 as it was before, so i guess i wont worry about it then, thanks sharpxmen!

I put a small amount of oil in the throttle shaft bearings, that's the only place I can imagine your oil came from.  That's why I recommended cleaning it off and keeping an eye on it.

Thanks BH, I hope it came from there, I will wipe and keep an eye on it and will update
if i see it again.

* To those who are wondering how BH can put oil in my TB throttle shaft bearing-The TB and TB Spacer i put on was bought from him.
