  2. Jeep MK Compass & Patriot Forum
    I was on my way to work this morning in my 2014 Jeep Patriot, around 100K miles and 5 minutes into the drive the Lighting bolt warning light came on, and the traction control light.. and no matter how much gas I gave it, it only barely would move around 5 MPH. I was close to work so I limped...
  3. WJ Grand Cherokee
    I have an '04 WJ with the 4.0L engine. The Jeep is in excellent condition after just turning over 80,000 miles. A couple months ago, I began to notice a high pitched whistling noise when the motor was at idle. The noise does not happen under throttle. The noise occurred intermittently at...

  5. WK Grand Cherokee & XK Commander Forum
    Hey guys, I've been doing weekend maintenance, and a couple weeks ago I took the air intake tube off and sprayed the throttle-body with GDI Intake cleaner. I was manually moving the flap, which I later found out was a bad thing to do.... Anyway, once I put it back together and drove it to blow...
  6. YJ Wrangler Technical Forum
    Hello all, I am in need of some help. Been doing some updates/maintenance on my 93 YJ 2.5L. Changed the fuel pump and drove her over to my friends garage (it's heated) to change the water pump and fan clutch. Got everything back together and when I started her up the RPMs shot up to 2900-3000...
  7. WK Grand Cherokee & XK Commander Forum
    Hi all, I have a 2009 Jeep Grand Cherokee with the 3.7. (117k) I recently changed the spark plugs and put a drop in K/N filter. I was reading on the forums and noticed that people attempted to do this upgrade and was wondering what the performance upgrade actually is? I know the PowerTech V6...

  9. Engines & Drivetrain
    Hello all, I recently changed some gaskets and when I put everything back together the engine had a rough idle and when in drive it wouldn't accelerate. I had 3 different error codes. P0123 P02111 (forgot the last). The issue was the TPS (throttle position sensor) was slightly unplugged. A...
  10. Jeep MK Compass & Patriot Forum
    Hi, all. I own a 2008 Jeep Compass (automatic transmission) with about 53,000 miles on it. I'm thinking of replacing the throttle body because of some recent issues I've had, but I'd like to get a second opinion on it first before I spend money on something that might not solve my problem...
  11. TJ Wrangler Technical Forum
    Hi all, Was wondering if anybody has found someone that carries a gasket for the IAC housing. I have a 99' with a 4.0. I'm going to clean out the throttle body this weekend, but would prefer to put in a new gasket rather than silicone. I called the local Jeep dealer and they can't seem to find...
  12. YJ Wrangler Technical Forum
    I cleaned the throttle body and the IAC the other day. After I was done I washed the engine to try to find the source of a leak. I didn't cover anything up :facepalm: Since then it has taken a lot of cranking to start (5-10 seconds) and then it idles extremely low, near stalling until i give...
  13. TJ Wrangler Technical Forum
    Hey everyone, I was teaching my girlfriend stick today and of course it was quite a bumpy ride. She almost stalled it and saved it by mashing on the gas and as she took it out of gear, into neutral. The engine keeps revving at around 2500 rpms. As I was driving back home I noticed that the brake...
  14. YJ Wrangler Technical Forum
    Hello, So I pulled off a throttle body from a 4.0L '96 cherokee at a junkyard. I tried to swap it onto my 2.5L and I've ran into some problems. There is a little nozzle on the east side that looks like a vacuum line. I don't have a hose for that. So I plugged it. I replaced the sensors with...
  15. YJ Wrangler Technical Forum
    Greetings everyone, This is my first jeep and kind of a mess so forgive any ignorance on my part. I just picked up a beat 95 yj 2.5L and need a diagram or picture of the throttle body connections, mainly where a couple of the vacuum hoses go. I have been finding more and more vacuum hoses that...
  16. YJ Wrangler Technical Forum
    I have a 1990 4.2 wrangler. I was wanting to do a Howell ETI conversion. Do I need I do anything with fuel lines, pump, tank or anything? Or will lines come with kit? I've been trying to research but can't find valuable information.
  17. YJ Wrangler Technical Forum
    I have a 95 YJ (stick shift) and whenever i drive slow like 1st/2nd gear and not putting much gas i get this terrible thrashing and jolting. The only way i could make it go away was to put in the clutch and let it out slowly giving it more gas. So the only real problem used to be parking lots...
  18. XJ Cherokee Technical Forum
    The first one is a hose that has a cracked end. Is this a CCV hose? Does this end need replacing? I was wondering what that is in the second picture. Can I get throttle body cleaner on that little rubber hose that comes out? The third picture I was wondering if I could spray throttle body...
