engine

Does anyone else have a really loose steering column, like to the point that its difficult to drive on the highway because the wheels go all over the road and you cant feel it in the steering wheel. Like its so bad that i cant shake the steering wheel pretty violently and the car wont turn at...

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...

Hey guys, ive diagnosed my engine light and its coming up with error cod P0133 which has to do with the oxygen sensor. does anyone here know how to fix the issue and diagnose whats actually causing the light to come on?

my engine light came on today. the engine doesnt seem like theres anything wrong it sounds all normal. but when shifting into or out of second gear it almost always grinds, this has been happening for a couple months. does anyone know what the engine light is or how to diagnose it? any help is...

Having trouble with my TJ not been able to get it to turn over. The battery is good so it’s not that but wondering if there is a place I can wrench onto to manually turn the motor over and ensure it’s free. Thanks for any help!

I have a 4 cylinder TJ on a 4" lift & 33" tires. I've been thinking about a V6 with a super charger because I don't want the weight of a V8. I also have plans to upgrade the axles so I can run larger tires so the new engine would have to work well with future upgrades. I'd like this Jeep to...

‘97 4.0 Manual 136k miles. Have this ticking noise when accelerating, gets louder with more throttle. Mechanic said the noise checked out and was normal but I can’t seem to agree. Can I get some thoughts on what it could be? The video I have was from today, in 3rd-5th gear, accelerating...

Hey, So I’ve got something that has progressively gotten worse over the course of the past few weeks and it’s the rattle grinding noise coming from the engine/trans area. The noise is never present at idle but only when in any of the five gears and I’m cruising but on the gas still. Transfer...

I bought a 2001 TJ Sport 4.0 about a year about with a replaced WJ inside. It drove perfectly fine up until about a month ago. Started getting a small 'lifter noise' that would come and go, nothing too bad to the point it was annoying. However, I tried to start the TJ after leaving work and...

I have 2005 tj 4.0 auto keep getting codes p0339 & p0300 I have changed the camshaft and crankshaft sensor, full service change of plugs & oils etc, injector clean and currently have a ignition capacitor on order hoping that would be the weak link. it runs smooth when start up and idling...

I've been looking into swapping a 5.3 Gen 3 engine to my 99 Jeep 4.0 Thinking of keeping the AX15 Transmission and Original Gauges. It is A LOT of work for sure to do all this, any of you know who does these kinds of swaps around DMV area? And how much? TIA

I have driven my jeep tj without a thermostat for 4 months and i opened my valve cover for leaky gasket and saw very bad sludge inside. Tried out engine flush of liqi moly but that didn’t work out. what should I do?

Just driving around and the indicator line is slightly past the 210. Don’t know if it’s overheating or if this is something that’s normal. Mind you, it is 95 out right now but I don’t know if that plays into this.

I bought this engine from a company that's supposed to be "refurbished" but the intake valves are rusted and a buddy of mine told me that this engine is toast so I'm here for a second opinion. Will this engine run if i just throw it in?

Ok, newbie here.🙋‍♂️ So, I'm one of those guys that used to ask why every five seconds about everything because I'm curious. Its struck once again. I was window shopping for a camshaft, not saying I'm doing one, just curious as to what there is out there for the 4.0. Naturally I checked out...

I’m about to begin the 5.3 swap on my 99 tj. It has the AX15 5 speed in it and I would love to keep it In the Jeep but not sure it’ll hold up. Does anyone have any experience with these transmissions being mated to a v8?

I attached two videos of my jeep. Both videos are at the same time but just a sound comparison. I also took off the belt so that way there weren’t any other sounds or noises from the parts all moving. I did an engine swap in January from a local you-pull-it. The motor itself has 120000 miles on...

2004 4.0l 42RLE (auto) Sahara Engine turns over very very slowly. Won’t start up though until I give it enough gas durning the start up and then and only then it will run smoothly. No rough idling but RPMS drop fairly low while at stop lights? Any thoughts??

I got a knock when the foot is OFF the gas pedal. It’s definitely coming from the engine. 2.5L 2001 tj with 187k miles. The knock calms down a little bit when warmed up. Any ideas?

GF helping me show it off haha. This’ll be my first car. I found my dream 2002 Jeep Wrangler SE. The owner is the 4th owner who got it at an auction. It had been in a collision in which the insurance company deemed it a “totaled car.” Apparently all it needed was the bumper replacement. I...
