Just got car back from garage. Now it's missing/sputtering?

[Boxcarracer944]

I just got my car back from the garage, I got some headers and a mid pipe put on. They did a great job of putting it on but in second gear and up it sputters a little bit when I'm driving it casually. If I give it full throttle first gear red lines fine, second has some trouble, like as if it is miss firing. Same goes with 3rd and 4th. And another thing, if I cruise it really low RPM's like 1000-1500ish it will shake voilently, and It never used to do this because I'd always cruise like that to save fuel.


So, is it a bad plug wire? What's the easiest way to check which one it is without replacing them all?

Thanks.

What headers did you get,LTS,MDL? brand?

Did you get the 02 extensions? More info will be help full.

i'm thinking your mech. broke a plug or a wire putting the headers in.or maybe you did it when you tried to remove them. real easy to do if you don't take em out

If it was a fouled up wire / plug you would notice it at idle. (corrected below)

Is it the MAF? I had a bad one and it made my car run like crap! All I know!

ehhh if its a plug or wire sometimes you only notice it when it's under a load...

Bassani shorties and h pipe

This sounds exactly like it. When I try to push it on low RPM's it can't handle it.




Whats the easiest way to fight out which plug or wire it is? Or do I just replace them all?

Its pretty confuse.
Ill pm this thread to a buddy to see his Opinion on this. :thumb:

there is no real easy way to tell which plug is bad. a temp gun aimed at each header tube and find the cold tube and that is the dead plug/ wire. but most peeps don't have that tool so just change all you plugs or wires which ever is cheeper or older and if that don't fix it then change the the other.

 

[Boxcarracer944]

Found it. Bad plug wire, changed them all. Well last time I take my car to that garage.

To be fair , it could have happened if they pulled the plug wires off out of the way, it could well have been on its way out sooner or later.
There are some crap garages, but it does'nt sound like they messed up because they were useless.

Glad you figured it out dude, it's a bitch when you pay someone to work on your car and you get it back running shittier than it was before, pisses me off beyond words.

 

[CC'S95GT]

glad you got it fixed. like said before the wires were prob on the way out anyway. can you tell any diff with the new headers

 

[Boxcarracer944]

I'll tell you as soon as theirs a dry day. My brother has a WRX and he gets me by like a car length if that. So maybe the headers will put with him.

 

[OnyxCobra]

What's done to the WRX?

 

[Boxcarracer944]

Not much, stupid bolt ons like BOV, and intake I think.

back when i just had exhaust and all my friends liked racing from a roll i raced my friend's 03 WRX from like 60 on the highway. I dropped it in 3rd and he slowly pulled me until i hit about 70 and then i walked right by him. You should be able to take him now i would think.

 

[Boxcarracer944]

Main problem is he has awd. He kills me off the line but as soon as I get goin he doesnt gain an inch.

He tachs it up to 4 grand and drops the clutch and doesn't spin.

 

[OnyxCobra]

I still think if you raced a full 1/4 mile you'd pull a Jason Lezak.

for a stock WRX all most 5.0s need are gears, and CAI. STIs on the other hand..... nitrous.
