back pressure?

[cornerkid322]

strange thing happening lately, when i put my car in reverse or when i put it in 1st, and i am letting the clutch in while giving gas, the car seems to bog down even when i give alot of gas, and to stop it i have to push the clutch back in and rev really high to get going. i think it could be due to my 2.5 inch exhaust and lack of back pressure. maybe?

Does the tach almost drop to zero? Are you stalling at all?

Im assuming that it wasnt doing this prior to installing the exhaust....correct?

Have you done anything else to your car other than the exhaust?

no not really just an alignment and new control arms, well actually i was messing with my idle but i think this problem has been going on before that though

lol back pressure its a myth...Look it up its been discussed. Find a vacuum leak.

welll i messed with the idle two ways: one- out of haynes they say to adjust your idle spped, it requires unplugging the IACV and adjust the screw on top of the TB. then after that didnt do anything, i just adjusted the throttle cable. idk

Like Nail said, check for a vacuum leak..

Other then that, what is your current idle RPM's? Later
