would a bad lifter or bent pushrod cause my car to run like crap when accelerating? my car runs fine at idle but when i accelerate around 2k the car starts bogging and i have this tick comming from my passenger side of the car. i checked the plugs and they are tight but the coil packs(the thing that bolts to the valve cover) are just hanging there,, im going to mount it back up tommorow and see whats going on, but i was hoping you guys could give me some info before i start ripping the block apart.

 

yea, the bent push rod could def. be the problem, take off the valve cover and see whats up

 

It could possibly be a bent pushrod... Do you get an SES light when the studdering happens, or at any other time?

 

nope, the only code im throwin is a knock sensor code and thats cus the rear bank is bad. but other than that. no codes

 

the car sounds pretty healthy too, just the car is bogging down when i try driving it and i have a tick that comes from the passenger front like every 10 to 20 seconds

my car idling

 

Usually, the pushrods won't make your car "bog". They tend to take power down across the board (most noticible in the higher RPM range 4500 up-trust me, 1st hand experience) and as far as I know won't throw a code. To me, it sounds like that hanging coil pack might be your issue. If it's not that I would look towards something dealing with your fuel or breathing.

I would suggest getting a dyno that has an A/F ratio graph....a good tech could probably give you a good idea what's going on from that.

Good luck.

 

above 4k is when my car is running the worst.

 

What are all of your modifications?

 

its a 382 with ls6 heads that have been ported and polished.
a nice size cam and stock intake.

 

....you could also be floating valves.
Really, to hard to tell without seeing/hearing or a lot more information.

 

i took the car apart today... it was a valve

 

Glad you figured it out!

 

i found a brokend valve spring, so im replacing the valves too
