once again, check your ignition timing

how? timeing light and see were the marks are on the lower pully? i only ask beacuse thats how it was on my old chebbie

only thing in system to check sides is the o2 sensor one per bank (left side - right side) o2 sensor $ 30- $ 80. and yes check timing.

Lean condition- clean MAF and look for a vacuum leak.

Pull the spout plug, put a timing light on the crank pulley and it should be set at 10 degrees. Timing cover must be in place,

worn timing gears/chain stretch is my guess. try to adjust your ignition timing

Timing is not adjustable on a 4.0L....

thats what i thoughts. ill check the timeing tomorrow at lunch.

if the timeing is right, what else could it be? messed up injector?

Could be a bad injector that is leaking a ton of fuel.

Have you pulled the plugs to see if any one of the cylinders is showing a rich or lean condition?

i did plugs yesterday and all the passenger side plugs were fouled, the drivers side plugs were burned whiteish brown

timeing is dead on, i cleaned the maf and it was better. its acting like im beaing starved for fuel.. the cats are no longer heating up to beaing cherry red.

 

[feellnfroggy]

The white side is running lean and hot, the other side (fouled ) is burning oil. Sounds like you have more than one problem. Also you cant adjust ignition timing, but you CAN adjust cam timing cant you?

 

[PaleBlue90]

i pulled one plug from each side and there fine. no fouling or anything.

 

[PaleBlue90]

its still got no power, the fuel filter was clogged and on backwords. i cleaned the MAF and checked for vacume leaks and were good there. timeing is good. i need a o2 sensor on the right bank, would this cause me to have no power?

 

[PaleBlue90]

well i guess im going to take it in for cat replacement
