I had the same problem. My engine would sputter between 1600 rpm and about 3000 rpm. I took it to my dealer and they replaced the plugs and wires w/ NKG'sfor about $60. They said that eclipse engines run hot and most plugs and wires olny last about 15-20k.

 

I just went and took it for a spin.
I clicked it over to high boost and floored well as soon as i hit 14 psi. she missed. I thought it was going to backfire. Whats up with that.

 

It still sounds like an ignition problem.

 

So what do i need a whole new ignition. How are the msd-2.
I also just changed my plugs to a new set and it was still there.
Anyother suggestions before i go buy one of these?

 

What kind of plugs are you using and what do you have them gapped to?

 

Im using ngk's .028. Its never done this before. Just trying to figure it out.

 

I am having the exact same problem.

I just changed my plugs and wires. I am using Magnecors and NGK BPR-6ES gapped to .03. It does not hesitate when accelerating hard. It is more like when I am cruising at 50 mph and lightly get on it; it sputters.

Possible problems I found from searching:
1. I know some people have had problems with the magnecor wires?
2. Fuel filter - but the car only has 42k miles?
3. bad coil pack?
4. I did a fuel pump rewire a while back; maybe I am running too rich or would the FPR not let it run rich?

 

Well i put the old stock wires back in a she runns fine now.
That is the 2nd pair of magnacor wires i dont think im going to buy them again.

 

Yea, I wish I did not throw away my old wires.

But anyway; Has anybody ever checked their Magnecors with a volt meter?
What ohms should I be looking for for each wire?

Hopefully I can do this instead of buying a new pair of wires just to check them.


Thanks in advance
