There is a schraeder valve on the fuel rail to check pressure. Should be 39 psi or so. Just pull all the plugs and look at them. And post a pic for feedback.

Dang no spark plug wrench lol. Know approx where on fuel line? Normally wouldn't mind crawling around but snow/ice/rain mix isn't as fun lol

So now that I hit the IAC when driving it the idle got worse and is inconsistent at idle. So I think I'll replace that for good measure. Any good or bad brands for them?

Hopefully you can still get a Mopar IAC.

so checked the spark plugs-ish haha. no socket but yanked the wire out and good s*** it's covered in grime, and fresh grime mind you. Don't know if that's all the problem, but would be willing to bet it's probably not helping any.

planning on ordering new plugs and IAC on rockauto. Which one(s) should I go with? was thinking the STANDARD MOTOR PRODUCTS Part # AC68 or IRTEX / WELLS Part # 2H1091 for IAC and for plugs the BOSCH Part # 7957 super plus with the.035 gap. Any objections or better suggestions?

oh, dude... those plugs look nasty.. It looks like a possible valve cover gasket leak plus heavy corrosion on the plug's electrode.. Definitely looks ready to replace. I don't know what it is supposed to be for the 8 cyl motors, but I could've sworn it was .040" gap? One of you 5.2l owners will have to chime in.. As far as brand, the plain copper cheapos from any auto parts place usually works pretty good from what I've heard. I believe I went with the mid-level Champions plugs(~$3.50 each from walmart) and they work like a charm for me, never had a problem. They were supposed to be pre-gapped but I had to redo it anyways, half of them were wayy too high or too low a gap.

Edit, if what you had before was working fine until recently, you might as well stick with it. It looks like champions? That name gets thrown around a lot here from what I've seen. Cheap, works just fine, copper core, good enough for a Jeep. One thing to note, don't bother spending for the premium $15 per plugs, and stick with copper plugs, not the platinum or anything

They're at least 4 years old sure that doesn't help. Gap is .035 (according to this site in searched it). Good to know to check gap no matter what tho

so best place to find a mopar IAC? did a google but wasn't finding much. I've read so much on these being picky with the mopar sensors rather just get one and be safe.

Gap is definately .40. Just changed mine and wires. Just put a set of champion coppers in it and a new set of wires. I think it was like $40 bucks and it runs like a top.
