Can anyone help?

Can anyone tell me why the maro is bogging down in drive and overdrive and not in 1st or 2nd gears...I just replaced the tranny, had the timing checked...when u take off kinda slow in drive it doesnt bog down...as soon as i smash the gas to the floor its has nothing...is it fuel filter? plugs, wires, cap rotor?? cant figure it out and i dont feel like taking it to a garage and paying 75 bucks just for them to tell me its a 8 dollar filter or something...please help...sorry this is kinda long but any help would b greatly appreciated thanx

Sounds like your throttle position sensor, because you're saying it doesnt really go any faster when you hit the gas, right?

it goes a lil faster but it bogs out real bad

Sorry to sound like a newb, but what does bog mean?

That's when you press the gas, but the engine hesitates before the car revs up/goes faster or whatever.

do you know how to flash the car for error codes?

I started my own thread without reading this one. We are having the same poblems camaro91rs05. Tell me if this happens to you: at or above 200RPM it bucks a bit, feels like you're riding a horse...

your car doesnt cut off at 200rpm?? i hope u ment 2000rpm

ok for both of you, third and fourth generation camaros are equipped with on board computers that will tell you what is wrong with the car 90% of the time. With the third gens, you can use a paperclip and the DLC to flash codes on the check engine light.

Unfold a paperclip into a U shape with the ends close together. Then put one end in the two ports on the top row, farthest to the right. the check engine light should turn on and start flashing. the first code it will flash is a code twelve, it will look like this....

Flash - pause - flash flash - pause - pause -
flash - pause - flash flash - pause - pause -
flash - pause - flash flash - pause - pause -

ignore this as its normal. a code twelve is set anytime the key is on and the engine is not running. at this point start counting the flashes, if it flashes another code 12, there are no other codes stored. say for instance you have a code 42, the next flashes you see would look like....

flash - flash - flash - flash - pause - flash - flash -pause - pause -
(repeating two more times)

dont worry if you miss something, because each code is flashed three times giving you the chance to get it right. Once you do this, come back and post what codes you found, and we can probly help you much better.

it will look like this....

Flash - pause - flash flash - pause - pause -
flash - pause - flash flash - pause - pause -
flash - pause - flash flash - pause - pause -

HEY! You stole my explaination of how the codes are reported! I had that copyrighted...I demand royalties!

I already checked for codes. Like I said in my own thread there were no codes, but thanks for trying. What else would you recomend?

well, the only other way to make an educated guess is to take it to the dealership and have them hook up a TECH 1 and watch the data in real time. They should be able to see a sensors voltage changing erraticlally and trace the problem.

thanx for the help guys Im gonna try to check for those codes and i will post them up here on a later date...i appreciate the help...ill post them up on here within the week... :smile:

well guys i tried testing it for codes and what do u know nothing has come up the only thing i got was the code 12 you were talking about 89IROC&RS...i appreciate the help guys is there any other educated guesses?

Coolant temp sensor. If it is reading incorrectly your ECM will be using the wrong fueling table. Speed density systems seem to be very touchy about the CTS (TPI's). The sensor costs a wopping $7 at Advance and takes about 15 minutes to change
