Car stutters when it hits boost!
 

Ok i just got the transmission in my car, 96 talon awd manual, and when i drive it every single time i hit boost the car stutters and misses and the cel comes on but goes off when i let the rpm go down the plugs and wires look good, i can rev it in nuetral and it goes all the way to 7 grand without any missfire. Can anybody help me out with this?

Bad plugs or wires will stutter on load only also.

Theres no boost leak, and the MAFS is pluged in even unpluged it to see if it made a difference but it didnt checked the tps no it. I'll pick up some new ngks today to see if it will fix it.

What are you using for plug wires?

Re: Car stutters when it hits boost!
 

I think there stock plug wires or cheap replacement wires i bought the car with a trashed tranny then put one in and now it misses, stutters and backfires

Get yourself some NGK wires while you're at it.

Re: Car stutters when it hits boost!
 

I would check the gap on the plugs first, and inspect them. If they are fine then go to wires. If thats not it them check the timing ect. Little easy things then hard things.

Car is completely stock exhaust, intake everything.

Should have went to CarQuest or Bumper to Bumper, I think they are the only ones in kato that stock NGK.

I checked champion bumper to bumper they had ngk but not for my car just like adavanced and auto zone they dont have it for the 2.0 turbo. My plugs are supposed to be in tomorrow morning so i'll have to swap them out tomorrow afternoon.

i get my ngk's from mills fleet farm. they have the colder ranges too if you like.
check your injector plugs...they might not be seating and making good contacts.
one of my injectors plug had some corrosion. it fixed my misfire.
its nice to drive a dsm with no problems.

later.

Alright i got it fixed it was the plugs one of them anyway and they were 7s wich are 1 step colder, there suposed to have 6s in them. And the plugs i got are ngks but they have 2 prongs i never thought ngk did that crap, so i dont have to gap them.
