Someone explain to me how my 2000 wrangler that has no distributor and is all computer controlled can be friggen detonating..??? I thought that was the point of all this computer stuff. I can be motoring along at part throttle and then I realize that I'm hearing this thing pinging away.. dont they have knock sensors and stuff??
(I mean damn it's a straight 6 not a 12:1 race motor.?? WTF?)

I wonder if your crank sensor is bad.

I looked in our cataloging and did not find a knock sensor listed(4.0l). That being said I would have to guess
1. cam sensor
2. crank sensor
3. pcm
well bad as I hate to admit it I guess I will be letting someone with more knowledge and or test equipment look at it.

nothing has been done as far as drivetrain. pretty much bone stock with 98000 miles.. I have a new set of plugs.. but havent changed them.. (much to my surprise there is a rail with coils bolted on the top of the plugs..) I am still working up to this.. what the hell is wrong with good ol plug wires and a distributor??

No check engine light?
That thing is new enough that it will throw a light up if the gas cap isn't screwed on tight enough, so the computer should give you some kind of answer.

6 Coils that are directly connected to each plug is better than 1 coil connected to 6 plugs. The computer controls the firing of each coil directly..
its nice in the fact that the computer can really directly control the advance of the engine a lot closer with less moving parts.
If I could add that to my 360 I'm building I would in a hearbeat. .. then again I like simple.. simple distributor.. simple wires... simple plugs.. those coil packs cost about $110 each.. like $700 to replace coilsMy friend priced them for her Toyota Corolla...
