Car is Sputtering
 

ok today i was coming home from work and i was at 65mph and i dropped it in to 4th to pass on the freeway and then put into 5th at 80mph and the car started hesitating and sputtering it did it a little bit when i was accelerating now it does it all the time. it sputters now when i take off all the time and i didn't see any vaccum leaks, i don't know if it could be the valve cover gasket leaking into the spark plug holes, or if i need bigger fuel injectors.

my mods to help you out:
3in full exhaust from turbo back
cooleeze intake pipe and radiator pipe
blitz bov
intrax lowering springs
tokico shocks

can anyone help shed some light on the situation thanks in advance.

Any codes? Whens the last time u changed ur spark plugs and wires?

I could have swore I posted plugs and wires yesterday.

see thats what i was thinking too that it could be the plugs and wires but i haven't pulled the plugs yet cuz it was too hot and i have a car to drive for the time being. there aren't any codes, and i didn't see your post about plugs and wires sorry.

if your valve covers are leaking, it is most likely leaking oil right into your spark plaugs causing the sputtering.

When My car started sputtering it was the connection on my TPS coming loose. The locking tab is broken on my harness which is falling apart.
Im definately going to get a good one on vacation to bring back and swap.
If your certain about your vacuum, put a vacuum tester on the car anywayz just to be sure on the T connection behind the intake manifold and see what it does.
This is a pretty good idea of what you will see when you put the guage on and basic diagnosis for the readings.

ok just to update i bought ngk plugs and wires from ebay and i got it yesterday and started to replace them and notice the wire on the 6 plug was a little messed up and loose so i replace everything and the car is now running stronger than ever. thanks for the help.

your gas mileage will jump up too. when mine was sputtering i was getting 17 mpg and after the NGk plug wires on i jumped up to 22 mpg :)

I went with MSD wires..

I thought about the NGK's.

I think they are both good sets.
