ive noticed that when im at 6500 in 3rd and in 4th there is a stutter like its not firing it just happens for a little and then it will go again. i have no clue what this is, it just started to happen a day or so ago, if anyone has any advice on what this could be please let me know because it is really pissing me off. im going to see how fast my car can actually go and this just wont let me do that. ive had it up to 111 so far, i dont think it can go much faster, but im guessing about 120 or so. or i hope i should say so if anyone has any ideas, just let me know, its much appreiciated.



thanks

 

what year/model car?

check your timing
check your air filter setup

 

if you have a 79 w/ points dizzy then thats you're problem. mine was so off it was useless to rev over 5.5k.

 

When was the last time you changed the fuel filter?

 

Let's see...'85 GS, so I speculate that it's time to replace the fuel pump with a high quality, new gerotor technology (at least in fuel pump use...), guaranteed to feed even at 9000 RPMwith a monster bridge-port, Mallory Comp110 fuel pump. Why I just picked one up used from the Irving Connection just the other day. It's going into the 'CBird, though since the '84 rex is only going to be in my stable for another month...

 

i have an 85 gs, and i havent changed the fuel filter, i have one, but i dont know where it is. i dont have a chilton or haynes manual either. so if someone could tell me where it is, then i will be able to change it

 

right under the body of the car, in front of the driver's side rear wheel well. the stock ones are stainless steel type stuff.

hehehe.... its amazing what falls off the trucks these days.... with a little effort....

 

alright, thanks, the one i have is plastic, and it looks easy as hell to change.

thanks again!

 

not mallory. get a carter. everyone else is doing it.........

 

why not the holly one its only one arm and half of a leg

 

Because he's ready to break from the pack of sheep to a real fuel pump but can't afford an Aeromotive, so the next best thing at half the price....

 

Holley Blue!!!!!!!.... if you want your car to constantly humm...

 

Worry about the filter first, 99% of the time if the filter hasn't been changed in the past 5-10,000 miles, it's the problem.
