what causes hesitation around 4k rpm's ?

only recently (after a 300 mile rally) I'm seeing/feeling hesititation just before 4k, if I take the revs up to 4 and then ease off the throttle when I go to put the gas pedle down it will hesitate until I go about 60% throttle and then it will start picking up rpm's like it should. its really noticible in 2nd gear.

could this be fuel filter related ? or secondary related ? Ignition ? vacumme leak? not too sure my self, any ideas

just an opinion but my first thought was fuel filter

usually its the fuel filter but this sounds similar to problem my car had. It hesitated at 4k in 3rd gear and wouldnt go past 5k in third. It turned out it the catalytic converter was clogged so i had mine cut out.


change the fuel filter if that doesnt fix it clear your cat out.

I will check the filter, it has been around 15-20k miles since I replaced with a new one. what do I look for when cheking this ? color?


my exhaust is a 2'' straight through dual exhaust with no cats. hmmm

15-20K since you replaced a fuel filter, and haven't had to walk. You're a hero.

I was just under the car today figgiling with the exhaust for a unrelated deal to the thread and the fuel filter is brown. going to be changing that soon.
