engine problems

Hey, so ive got a 99 Sahara, 4.0, manual. every once in a while, when I start off, it makes a loud popping noise which im assuming is backfiring, and loses acceleration. What I usually do is just push down on the accelerator and power through it and itll go away. Any ideas what it is or how to fix it? Thanks for any help.

The first place I would start looking would be your aircleaner/filter. Ensure it's clean, and no obstructions. Second, I would remove the airhorn from the throttle body and while the engine is at idle, spray some throttle body/carb into the throttle body. Be prepared to grab a handfull of throttle to keep the emgine from stalling out when spraying. Then, I would run up the rpm's some and spray a couple more shots. After that, add fuel injector cleaner to your gas tank and then everyother tank, add a fuel addivtive that removes ethanol. Ethanol alone, is the ring leader for 90% of all carb/injector issues.This crap really gums up things and provides for symptoms you discribe. It may take a tank or two to clear up but, if caught sson enough and then follow prevenative measure's, you should be ok.

How many miles is on your Jeeps engine?

I had those problems and more
I have over 200,000 miles on the factory timing chain and sprockets
I just changed them out myself and all of my issues are gone.
Problem solved
The old chain and nearly 1" of slack in it.
The new chain had about 1/4"

Huge performance difference
