Since I had the plugs and wires done, I have a serious hesitation. I step on the gas I get a serious pause, kind of flat she may stall or not.

Under the hood, when I hit the throttle quickly, I hear a sucking sound, that seems to be coming from the area under and behind the throttle body, like a vacuum leak, I shot carb cleaner in the vicinity hoping that the engine would suck in the cleaner, rev a bit and give me an idea where the leak may exist, if it does at all. No luck.

I take off the throttle body, plenum and search for a cracked vacuum line ... Nothing. Damn plenums been on and off at least six time.

Any Ideas ?

 

wrong plugs I bet u put in bosh or something right?

 

No good ? Bosch Platnum ?

I think I read some where you said Champion platinum and OEM wires ????

 

no
champion only

 

K .... give it a shot tomorrow.

 

Ey, Chrys .. should I also chuck the wires and get OEM ?? Or just try the Champions - regular flavor ?

 

The sticker under the hood lists 3.

Which do you recommend ?
PFR5J-11
PK16PR-11
RC10PYP4

 

Ok RC10PYP4, Champion Double Platinum from Mopar, were installed. Definite improvement. But I caused another issue. The Top egr tube bolt holes are stripped I guess. They go in spin all the way in nicely, but dont grab and tighten. No biggy. Got the spare from the wreck.

After installing the plugs, I took it for a 40 mile test run. I did get two minor hesitations but I think once the vacuum leak is fixed, the issue should be corrected unless something else pops up, or the minor hesitation increased frequency and intensity. Will keep ya posted.

 

I know that Chrysler Tech said Champion, but I have found NGK spark plugs to be better. However, if you stick to OEM, you can't be wrong.

 

Jeeps use NGK. I will tell u chrysler fuel systems build there calculations around the spark plugs. If u change the setting u get stuff like what happened on this post.
