Did you try the knock sensor yet?

When my van's knock sensor went crazy, that's kind of what it did. The knock sensor listens for knock and retards the timing to keep you from hurting the engine. When it gives a false positive, it retards the timing which causes the vehicle to run bad on acceleration.

Other than that, you need to systematically go through the sensors to make sure they all work properly.

OK. All problems have been fixed. It wasn't the knock sensor, fuel filter or anything like that. It was the float level. It was set too low and hence wasn't getting enough gas. 25 minutes later I had it adjusted properly and bam, no more problems. She's running like a champ now.
Thanks to everyone for your help!

awesome! Glad to hear it's all good and no knock sensor issue!

First Jeep was an 1989 YJ, I've also had a Grand Cherokee. Currently, I have a 99 XJ.

Well, I spoke too soon. I can still smell gas, and I'm realizing that it had nothing to do with the prior issues with the carb. Doing a search throughout the forum however, looks like it might be a corroded rollover seal or that line canister line that goes up into the rear fender, above the exhaust pipe.
I'll look behind the brake light tomorrow and see if I can reach it. I hope it's as simple as replacing that!

Sorry for the lack of detail. I purchased a kit "K551" from Carbs unlimited. It's a 32/36 Weber. I recommend the kit because it includes all linkage and very detailed instructions. You will lose the stock air cleaner though but the kit comes with an air filter assembly. Not a big job, but quite a bit of vacuum lines will disappear as you make the swap.
