OEM coil or after market. Neons do not seem to like aftermarket coil packs. I would check your engine ground, spark plug gaps, if it is an arftermarket coil pack go to a junkyard and get an OEM one. Try OEM wires if they are run of the mill replacement wires, check gaskets and leaks around the inta...

How many miles?

Edit: 142,000, yeah, may want to check the overall condition, as part of the diagnostics.

Wouldnt bad compression affect the overall performance, it runs great once its going.

Jimminy cricket!!!!!!! I was looking up the price of IACs even on rockauto they are damn near $100.

thanks got her fixed, didn't go to bad considering i'm down to one hand, for the time being

so I've been chasing these gremlins since we got this car. So far I have put two new O2 sensors, a new cat on, and a couple of sea foam treatments, I saw the guy who i bought it from put a new coil pack and wires and plugs on. With that being said when i get to a stop the engine's rpm dip a little a...

(2002 2.0 liter) How common is it for a thermostat housing to crack. I was putting 02a sensors on the wifes car and i decided to check the coolant for some strange reason and when i put the cap back on i hear kind of a gurgling hissing noise and sure enough there was coolant coming out of the therom...

hmmmmm me thinks there is something with our car, we're getting about 180-200 miles to the tank so far.

I would continue to drive it for a little while before tracking down that code. Sometimes things like that "clear out" wehen it comes to the cats and exhaust when you put additives in. if it doesnt clear up in like a tank of gas or so then id start tracking. so yo uknow, if you turn the key on/off/...

So i ran a bunch seafoam through the vacuum and it helped it out. I drove it on the highway and got back into town and the CEL came on. I took to Advanced Auto and got it read and it was throwing a code for the cat. I told the guy that i seafoamed it and he suggested that some carbon got trapped in ...

how many miles? original motor mounts? how are the rpms at a stop? 142,000 miles, not sure the condition of the motor mounts, no tach but it doesn't sound like it's idling high mine idles rough too. looks like my antena is being shaken by hand it wobbles so much at a light. i can see mu upper passe...

We just bought an 02 Neon 2.0 SOHC base for my wife yesterday and I've notice a couple of things. 1. The idle is rough it seems to shake the car a little, no CEL, once you give it some gas it smooths out. I did notice one of the 90* elbow pieces that connect the vacuum line to the back of the valve ...

Hello everyone, I am starting this profile for my wife who just bought a 2002 Neon 2.0 SOHC. We just bought it yesterday with 142,000 on the clock. I was very impressed that it is so clean for having higher miles and being over ten years old. The plan is to keep it stock, and use it for a daily driv...
