    which engine?, spark plugs. air filter, fuel filter if external, hot and cold misfire , reeks of bad spark plugs since no engine stated i can say if car has spark wires, or COPS. (6 cops on 4liter.?) does the CEL glow key on, and does it then start glopwing when it misfires. cutting in and out , 100% lost power? then is the dash lossing 12vdc power, battery charged,? 12.6vdc rested. and 13.3v to 15v running? if the battery lugs (part of 60k) are dirty , DC power can be intermittant, and the EFI has and ASD relay that can drop out, this kills engine flat, (this is not simple park misfire, this is the relay drop and killihng all park , its easy to tell the engine starts to stall , ask drop fells just like turning off the igntion key driving.

    why is battery too hot, is it overchargin? bank 2 , S1B2 or S2B2. so you have a V6. due to bank 2, bank 2 sensor 1 Front) should not be ignored, or the right bank will run bad.

Seems like you might have wet the no 1 injector sensor..(little black plastic thing with 2 wires) It sends a pulse back to ecu and if wet it,s no good....

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

It could be a spark plug, plug wire, or a coil. Sometimes thay break down intermittently. If it needs a tuneup, that would be the first thing to do.

I have a 99 jeep grand cherokee ltd, 4.0 L, 6cyl, auto, 4wd, 87000 miles. My problem is that on the first start of the day and when the engine is cold, the transmission wont shift from 2nd to 3rd until...


I'd begin by having the trans fluid changed and making sure there isn't an excessive amount of debris in the pan (there is always some but should not be obviously a lot) You may have a slight varnish buildup inside that becomes less sticky as the internal temp rises.

02 Grand Cherokee High RPM start. Cuts out when driving


Ckean throttle plate inside throttle body...They tend to get dirtier than their counterparts in carbureted engines due to lack of fuel spray that kept them clean. If no luck with that, clean idle air control valve on TB. When doing this, don't turn the plunger, just clean with carb spray and replace. do not loose "o" ring seal.
Good luck

Engine light flashing on my 2001 jeep cherokee 4.0 and engine sputters on throttling.


It could very likely be a vacuum leak. Almost every runner hose on mine ('03) has split.

If you can get it to a auto parts store that has a scanning tool, then find out what the codes are. That will give you an idea of where to start looking for the problem.

Also had an Astro that started sputtering and popping at low RPM's. Turned out to be a piece of trash in the EGR valve.
