The coil packs never fail all at the same time. If you have misfires for all 4 cylinders, then I doubt its directly ignition related. It would have to be a fuel/air issue or possibly a bad ICM for pre 00 engines. Even when the ICM goes though, normally its a cyl 2 misfire, and hardly ever all cyl's.

 

yea im gonna clear them...
the mis fire is only on 3 an 4 not all of them...
im just trying to find my boosting problem..
hopefully nothing major...

 

I doubt you currently have a misfire, if you did, the engine would stutter hard and youd most likely get some backfiring along with a flashing CEL. You havent complained of any of those things which is why I think the codes are old news.

 

I put in the speedtuning chipped ecu tonight. I didn't take it on the highway, but on the back roads it haulled *** in 2 and 3. I didn't want to take it too much beyond that because it's been raining and freezing rain and snow so the roads are slippery in spots, and I don't want to end up in a ditch too. It's all hills around where I live. When I get it out on the highway tomorrow, I'll see what it has for sure. I post up what theboost spikes to and holds at. Anything else anyone wants to know about this chip? just post and ask me.
I know it got over 18 psig tonight, but like Isaidthe weather wasn'tgood for maxing out the car, plusI gottaget used to the new power curve first. It'slike a new car, unpredictable until I getused to it again. still handles like an old car, but I've got something lined up for that -a project between Christmas and New Year's when I'm off work and[sm=partyparty.gif]new shocks, springs and complete front control arm kit.Still haven't decided on which to get yet.

 

glad you got yours in bogie, make a new post with a complete review for me would you? Seems like it's going well so far, so I hope that continues...

 

well, the coilpacks are better on the 2000's, and heat isn't a problem in Ct this week. It's been about 25-35 degrees F.The car felt good this morning definitely holding at 16 psig with the Forge 007P DV with the yellow spring. I couldn't really get on the gas 100% this morning either - commuter traffic [:@]. I'll start a new thread and post more info when I get more time driving it. But I like it so far.

look at the pics and description, it does come with the rubber...

 

I am debating doing this and I have one simple question: has your car's gas mileage changed much? Thanks!

 

Gas mileage in my car is still anywhere from 32 to 25 mpg, depending on how I drive and shift, with 91 or 93 octane.

 

Thats very good to know.. I guess I'll be ordering one as well =D
