Hey y'all,
Last year I rebuilt the 4.0 on my '89, but after screwing around with it I got frustrated and left it sit for the last few months. Here's the deal>
The engine starts great. Seems to idle great. Idles around 5-600ish rpm. When I give it gas and the rpms get over about 900ish, the motor starts to sputter and bog down. I've replaced the CPS, all the vacuum lines are new. I've checked and rechecked the distributor, I don't *think* I'm off a tooth. What else can I check?
Edit: The jeep will not accelerate at all, if I keep on the gas it just bogs down, sputtering and backfiring. The engine doesn't actually die, however.
Thanks,
Tony
