That missing, coughing, thing- ELE. CHOKE WIRE!

Have '89 YJ. Carbed 4.2L. Started to briefly stall then quickly progressed to point that would hardly run. It coughed, sputtered, missed horribly and generally was one sick Jeep.

New plugs. At first thought I fixed it. Ran better. Drove it. No problem. Smugly patted myself on the back.

Sat a couple days and when I started it was worse than ever.

I scoured these forums and found a bunch of possibilities. O2 Sensor, CPS, CAT, timing, fuel filter......I'm in over my head.

So, I took it to my "guy". He's the guy that just knows cars. Anytime I take something to him he finds it the first time and fixes it cheap.

And he didn't let me down this time.

I was ready for 2-3 hundred dollars minimum. "Let's try this...could be that".

He nailed it the first time. Bad electric choke wire. Charged me 10 bucks. Ran great now for a couple weeks.

So.....I offer this as one more thing to think about checking if you have this problem which seems to be fairly frequent.


Hope it may help a fellow Jeeper.

Re: That missing, coughing, thing- ELE. CHOKE WIRE

I'm interested in how the vehicle ran with the: <ul type="square">[*]Engine Cold[*]Engine warming up[*]Engine at operating temp.[/list]You should have seen differing symptoms as the inoperative choke was not adjusting the fuel input for engine heat level. Do you see symptoms change with warm up to operational temp?

Yep I did see differing symptoms based in retrospect on temp. and maybe airflow.

Had failure 4-5 times right as I shifted into 4th gear.

Not sure why...but I suspect it was because of airlow and/or temp. change not the change in gears.

In any event it's fixed...so far

One other problem that can happen that gives a similar symptons.....

The intake has a heater built into it right below the carb...this is fed by a relay on the firewall.....

If the relay goes not, it starts ok, but it takes for ever to warm up....really bad in winter.....
