You should, in no way, take any of this personally. It's just business. So to recap, I come in peace, I mean you no harm, and you all will die. Gallaxhar out.

Did this except for fully removing the IAC housing (no security torx bits). Scrubbed the throttle body and used several qtips on the IAC housing. Jeep idles steady and found some get up too. Thanks fishinjeep for the great write up.

I used this walkthrough today when I cleaned my throttle body. I could t get mine as clean as the pictures, even using a tooth brush and going over everything a few times. I think a polishing bit on a dremmel wouldve been good to use.

I have 97 TJ 4ltr with about 113k kms, which is about 72k miles. It runs fine but sometimes takes several cranks to start. It seldom starts on the first key and almost always on the second key. New HT coil, distributer cap and rotor and leads fitted about a year ago, and fuel pump and some lines, also about a year ago. This was for severe misfiring and farting and the pump cleared it up. Any advice regarding the starting?

I will take a look at the throttle body and appreciate any other direction that might lead to a cure.

Thanks,

Slow starts are normally caused by a leaky check valve inside the fuel pressure regulator. Did you replace that at the same time the fuel pump was replaced?

That problem is so commonly caused, primarily, by the fuel pressure regulator and, secondarily, by the second check valve inside the fuel pump, that I wouldn't look beyond those two possibilities.

Thanks Jerry, I will take a look. Are these components at the pump/tank end of the lines?

IAC still acting up

I took my carb off a few months ago and cleaned the IAC valve and it seemed to work better. But then a couple of days later it started acting up again. I have a manual transmissin and when I shift from 2nd to 3rd it seems like it wants to die. It bogs down real bad. It idles fine, I changed the idle control a few months ago. Any way....I replaced the IAC and it still seems to have the same problem. When I am driving, it seems like it is starving for fuel. I know it isnt the fuel filter because I replaced that a few months ago when this first started. Could someone please help?
