I have a CJ5, 4 cylinder that "cuts out" while I am driving down the road. It doesnt die, just "coughs" as my wife puts it....any thoughts or ideas?
We are new to jeeping and just went through emissions for the second time, first time failed the pressure test. I changed a few hoses and got a passing grade. Ready for the road but would like to figure out the issue of cutting out. Doesn't do it all the time, mostly intermittent.
Sounds like it might be running out of fuel do you still have the emissions report tell me the readings could also be in the distributor is the timing set correctly when was the last tune up and what was done to it check the fuel filter
I would start with a tune up replace the spark plugs wires,spark plugs, distributor cap,rotor,pcv valve,fuel filter, check the timing, adjust the carb to start with the carbon monoxide is really high its actually over fueling the carb might need a rebuild or you have internal eng problems also if you have a compression tester check the compression it kinda seems like camshaft is going flat I would start with a compression test first before anyrhing then let me know what the readings are
I changhed the distributor cap, rotor, and PCV valve and thought I had it fixed. foound a post on the distributor cap broken off. Ran it for about 20 miles total the last few days and it started to do the same thing. I dont have a timing light or a compression tester, the plugs and wires are almost new. The carb I was told was recently rebuilt. I will look for the fuel filter, didnt check that as of yet...
Still trying to figure this out.
Well I think I, we, figured it out. Remember I havent with mechanical stuff for many years. I am a Paramedic, not a mechanic...haha! My neighbor has a friend who is a "jeep expert", so he came over and bottom line was I would exchange the carb since he felt it was a fuel issue. My neighbor, who is as much of a mechanic as myself, asked about the fuel filter so we checked the fuel filter and it was plugged, $1.50 for a filter, (I got a spare just in case), put it in and runs like a champ! Go figure...
I appreciate everyone's advice. I look forward to tinkering with this CJ5 for a long time...
