Just today after fueling up, my 1988 XJ started "stuttering", like in first gear it would have some power, then lag, get it back, and back fire and same in the other gears. Thought maybe vapor lock, but it would backfire with the gas cap on or off and continue to "lag" when applying gas. It does...

Bought a 1980 CJ5 a year ago and have been working on restoring it. Currently not Pulling any fuel to the carb. To diagnose, I started by checking the lines and sure enough the lines at the tank were dry-rotted. Ended up doing a new tank (with fresh gas), new sending unit, new rubber lines front...

Does anyone know the thread pitch and diameter for the mounting bolt that holds down the fuel pressure regulator? Mine snapped in half when installing a new regulator. Thanks.

I need help guys, I’ve spent thousands on trying to get this sorted no mechanic can find the issue I have a 2014 Grand Cherokee with the 3.6 petrol, I have a check engine light for a p2098, I have done everything, had smoke tests done on the exhaust and intake, I’ve change o2 sensors I’ve...

Hey guys, I recently replaced my fuel pump on my 97 TJ. When I replaced it I noticed the gage when the tank is full only reads half a tank, and makes it’s way to “empty” with a half tank still left. It even drops so far down that the gas light turns back off haha. Not sure if there’s any...

I'm looking to purchase a fuel pressure regulator for my 4.2 with a Nutter Bypass and a carb without the motorized stepper crap on the back of it. I see Holley makes one but it has dual outlets and only goes as low as 4.5lbs. Carter makes one that just uses a chrome dial. It seems a bit...

I just installed a new precision brand mechanical fuel pump in my 1989 Jeep YJ Islander. It has a Weber 32/36 dgv carb and inline 6 cyc engine. When I start the carb is filling up with gas and running out the overflow tube. Some background: Jeep was stalling at stop lights and slow...

'99 WJ 4.7L 159,000 I have noticed a stalling issue with my jeep lately. It starts up fine, no issues. It idles at 600 RPM, no problem. I put it in gear and drive off, great. As soon as I let off the gas the RPMs drop and the engine shuts off. I then limp it back to park it. I start it up...

Background: I was driving on a feeder road about 50 mph and a truck clipped me sending me swerving off strait at a curb. Hopped the curb, bent my axle housing and was still able to drive to a shop. Ever since then my jeep has been idling rough (250-500rpm) or dying. It is running very rich and...

It's my first time on the forum so I apologize if I'm being to vague. I have a 1987 Jeep Cherokee XJ, a couple nights ago I was driving down the road and I smelt something foul coming from my vents, almost like a burnt smell but not a burnt smell I could recognize. I thought it was strange but...

Hi, I have a 1994 jeep Cherokee 4.0L and I wanted to know if I can put a new fuel pump assembly that from a 1994 jeep Cherokee 2.5L into my Cherokee 4.0L?

Just as the title says, it seems I have an unfixable issue. Have had my XJ for about two months now. Drove beautifully for the first month and a half, but now it's getting weird. Basic specs: 4.0L 6-cylinder Roughly 184,000 miles Stock parts all around Down in Houston, we had a real hard...

I'm working on a frame up rebuild on my 79 CJ5 and I'm pondering how to better capture gas fumes. I've always hated OEM charcoal canisters. It seems like there should be a good generic universal replacement especially for older applications. Something simple and serviceable. That way if I...

I have a 1984 CJ7. The engine (inline 6, 100,000 + or -) runs fine around town. Can not hold 55 mph or get up a hill over 45 mph. I replaced the old Weber Carb with a new Weber Carb and fuel pump. I did the nutter bypass. Still the same issue, it runs well at light pressure on the...

Good Evening. New member here, I've joined to get info to help while my son and I fix up his '93 YJ. We have been tackling a rough running rich fuel condition since he bought the jee[, and we think we came across something that I haven't seen while searching the forums. Sorry if I missed it but...

I have a 2008 Wrangler X, 2 door with 115,000 miles on it. Six months ago I began having misfires and a rough idle in my jeep. The check engine light eventually came on and and the misfires became constant. Took it to my mechanic and he found that fuel injector 3 was blown. He replaced it...

Hey everyone I have a 1995 yj with a 2.5l engine thats having a problem. I have searched around the forums and found people with kind of similar problems but not quite the same. So in the morning or after my jeep has been sitting for awhile when I go to start it the fuel pump doesn't kick right...

I put a new gas tank on my 86 CJ. I put around 6 gallons in the new tank. When I turn the key it cranks fine. This has a mechanical fuel pump. I'm not getting fuel to the carburetor. I used a pump to load the lines with fuel (sucked gas from the tank to the fuel pump). That didn't work so I...

Hi, I have this GC 2009, 3.7L AWD, no mods/stock for last 7 years. To knock on the wood I haven't had ANY issues with it so far. Just regular maintenance. It has 70+kmiles. I mostly use it for commute to work that is not to long, towing the boat (19 feet, 1 axel) and to play n the desert-and...

A few days ago my wk prompted me to "close fuel cap". It eventually was replaced by the check engine light. OBD reader shows p0456 (small leak). I replaced the fuel cap (old one was indeed not as tight compared to the new one) but the check engine light still persists after I drove two minutes...
