spark plugs

Ok super weird. Other than obvious signs of rods or piston movement...I don't hear any clapping or knocking... What other factors can lead to plug gaps shrinking from .035 to .031 within a couple of weeks weeks? 😬 I've been going through my TJ and tuning up different systems. Swapped out the...

About a month ago I got a 1999 TJ with 66,000 miles on it. This jeep is a right hand drive and is in great condition cosmetically. Interior was well maintained, frame is undercoated with zero rust. The gentlemen I got it from told me there was a sputter in the engine but it was still drivable...

So I bought this tj about 6 months ago. Drove perfectly fine for the last 4 months. It had 99k miles when bought. About 2 months ago when I would have less then half a tank it would take a couple key turns to get it to start. I figured maybe the tank wasn’t vented properly. But I looked into it...

Hi from Rome, Italy where I converted my 1999 Jeep Wrangler 4.0L in a LPG powered to pass emission restrictions here and run everyday as a daily driver in city centre. I decided to make this post cause I can't really figured out the problem after many attemps. Symptoms are some little random...

Stalled in the road after getting gas a few days ago. Wouldn't start back up. Towed it home. Replaced some sensors, coil pack, etc. After returning all of the sensors, I noticed the fuel injector fuse had blown. Replaced it and it started up for a few seconds but with clicking coming from the...

Hi all, I have a 2000 Jeep with 157000 miles on it and I've been having some trouble with it starting and running. I've owned the car for about 2 years now and for the whole time that I've owned it It almost never starts on the first crank, but always on the second. there are some other problems...

To begin: (This is my first post here, so I apologize if this is in another thread somewhere, I tried to look around for one). Long Version (I'll try to put a shorter version below). Thursday I was out with a buddy and my Jeep died. I was in 4WD High, 2nd gear (I think), going 25-30 mph...

I have a 2005 TJ 4.0 and I joined for some help. I have a P0303 code which is cylinder 3 misfire. Things I have done so far include all new spark plugs, new coil rail, new o2 sensors, swapped the first fuel injector with the third fuel injector, and a new crank position sensor. Only thing I can...

I have a 2006 Wrangler and have been experiencing some stalling issue when decelerating. A few days ago the check engine light came on. I checked the diagnostic codes and codes said a mis-fire on cylinder 2 and bad O2 sensor at catalytic converter. The converter was also getting hot and the...

Compared to the vehicles I grew up with, the amount of ignition maintenance that is required on today's vehicles is almost non-existent in comparison to the engines from the 1960's. Setting the points, making sure the condenser was good, and chalking up the timing marks so you could see them in...
