Does a bad TPS cause an erratic idle?

1996 is still OBD isn't it? key on key off.....

I wouldn't be able to tell you. Once in a while my idle will be around 500 which is not normal, but that's all.

Here's that video I was talking about, pretty lame I know, but atleast you can understand what I mean.

(I read the other posts too, thanks for the replies. By googling, a fuel pump issue makes the most sense for now, but I'm still looking around for similar issues than mine. I'm just taking note of everything that is being said so once it's the time to check out the issue, I have somewhere to look first)


Keep in mind my position on the pedal is always the same.

Clogged cat?? Had the same symptoms on my pickup and turns out it was a bad cat

Cane

Will keep that in mind. From what I can read online, the issues I'm having share some similarities with those from a clogged cat, although it wouldn't explain the clicking I feel / hear.

Thanks!

You can't see the RPM gauge in your video.

Cane

It was dark, but the gauge I'm filming is indeed the RPM one.

As a side note, this is very hard on a vehicle. The engine doesn't come close to operating temperature in this amount of time. It just gets warm enough to build up condensation in the crankcase (and exhaust system), but not hot enough to burn it off. You would be much better off only starting your Jeep once a week, for example, and then taking it for a nice long drive. (Once your coolant reaches normal temp, it takes another 10-15 minutes for your oil to reach operating temp.)

If you have a '96 there is a lifetime recall on the factory cat. If you hear a good rattle when you thump it, it's shot. Local Chrysler/Jeep dealer can run the VIN and tell you if the repair has been made.

If you have access to a DVM you can test your TPS, and it wouldn't hurt to pull the IAC and give it a gentle cleaning. (don't get cleaner into the stepper motor)

Funny that you say this, I took it for a ride with my father who is more experienced than I am and he's pretty sure it's the cat that is clogged and that "click" I was getting is from there. Is that a possibility? Could it be the cause of my problem?

Thanks for the info!

Edit:

I just went on Jeep's website and entered the last 8 digits like it was mentioned and I got "No Incomplete Recalls or Customer Satisfaction Notifications Exist"

It is a 1996 cherokee, could this be an error or my vehicle is not affected?(I live in canada, maybe it was only affecting US vehicles?)

Radi

That's a possibility, I'm not sure if the recall extends to Canada. A call to your local dealer would probably be best.
