I would like to know if the 4.0L Jeep Grand Cherokee changed or developed their tune up kit, I was told that 4.0 Jeep Grand Cherokee no longer have distributor cap anymore and it has the coil packs instead since 1994. Please advise.

gas it will shift and somewhat recover my codes read 3 out 4 os are bad and 5outa6 cyl misfiring. if i change out the os will the cyl misfire dissapear? it also seems to have gas in the oil and just bellows out smoke not to mention 6.1 mpg

the gas it shifts and recovers still running rough my codes say 3out of4 os are bad an 5 out of 6 cyl. misfiring. do you think that changing the os will stop the misfire? i also seem to have gas in the oil?so it just bellows out smoke and gets 6.1 mpg?i havent done much new plugs and coil bar so far

The Jeep came back from a transmission place. As far as I know they dropped the pan to look at things. They replaced fluid, put pan back on. Drove car home and radio had died. Screen is totally black. Can't turn on the radio. Any suggestions? Is there a fuse for the unit?

What's wrong with my jeep grand Cherokee Laredo? My jeep had a leak in the radiator and then the engine started over heating. Replaced the radiator and thermostat took engine apart cleaned engine and replaced the head gaskets put it back together and tryed starting it well it started but there's a knocking in it and the piston isn't in the best of shape and it seems to work but it doesn't look like the sound is coming from the piston and it's still overheating I'm not sure what is wrong with it and i don't want to take it to a mechanic because I would like to fix it please help me figure out how to fix my jeep.

I just got a tune up, the serpentine belt replaced and a new fuel filter put on.

Jeep will crank over but will not start.

We have had the throttle control error come on twice now. Each time, the car started to drive slowly and erratically and all the systems (ac, etc. turned off). We have had it towed. Dangerous to drive.
I think the correction is to replace the throttle control computer. Is this correct? The last time we had it in, the guys thought it was a loose wire, Clearly not. It is now being towed to the dealer. Help!

I took it to advance because check engine light came on. It said all for wheel speed sensor and g switch.

The code is showing a p0463 and wanting to know where sensor is located.

Codes: 303, 203, 158, 320! My cars symptoms are like what is described in many forums as being similar to both crankshaft sensor problems and camshaft sensor problems. My mechanic told me we should replace the camshaft sensor first. But the code referenced by ODB was crankshaft 320 not camshaft. In looking at all these codes together. Which would you suggest to change first?
