Help my car hesitates to accelarate when I punch it. Only when the car

has been on traffic and i try to punch, my car hesitates to accelerate. No

engine light is on? What could it be? 93 trans am A4 auto 108,000 miles.

When i accelerate normal or slowly it works fine, but when i punch it, it

hesitates and goes but it feels like its going to turn off and then goes?

PLease help!!!!!!!!!!!!!!

Are you hitting the rev limiter? my car does this at speeds under 30.

Its an auto so i cant hit the rev limiter unless i drop it to first and play with

it. Most of the times i leave it in overdrive(4th gear). I can only feel it when

there car has ran for a while and i try to punch it and it hesitates real

bad.Say im going 65 on the freeway, and then i punch it, it feels like it wants

to turn off and then goes and then it hesitates again, but when i accelerate

normal it works fine. My fans turn on, it has a new water pump, and a new





radiator, idk it feels like it looses power?

I bet it going to be you cap and rotor.. I had the same problem with mine .. I replaced eveything then when it came to the opti my cap was the problem .. Take off the opti and check the cap..

that or can be you maf going bad as well..

Yeah i think your right. What would i look for when i take off the cap? Could it be just the cap or the whole opti?

If it is just the cap, do i just buy the cap and rotor kit?

As for the maf sensor, it doesnt have one since its an 93 speed density.

look at the terminals and the rotor tip and see what color they are, this will tell you

ok il check that out. If by any chance it is the whoel unit. what do you guys think about this unit? It seems more than decently made? Plus it isnt 300+?

Yes I have that one and it works well. Others will likely tell you ACDelco but those are around 300. I've ran a chandler motorsports opti for 3 years now and its worked great.

Thanks bro ima go buy this one. do you know what warranty it came with?

Ill just say that autozone also has one for a decent price and has a lifetime warranty so no matter what happens they will swap it out. I have used one for over 4yrs no problems. Im not sure if that unit comes with the cap and rotor but if it does thats a crazy cheap price, and if you do have issues with it you only have 30 day warranty, vs a life time just saying.

323steel36

Which one has 30 day warranty? The autozone is the one you have used for 4 years? If i do need to change the opti what would I also have to change the spark plug wires connected to the opti? which wires do i get?

The brand new one from the zone is life time, get msd wires and cap and rotor kit. wires are 109 and cap/rotor kit 149

i think merv once said that he used the duralast brand at autozone with no problems before. Correct me if im wrong. They are like 40 bucks.

Whats 40 bucks? am i not reading your post right or something but what did the MERV buy and have good luck with?

95chevyz28

autozones wires...the duralast brand. I think they are around 40 dollars.

ok thanks for clearing that up. i hate those ones cause when they heat up they dont fire as good, there cheap and if you try and pull a plug when its kinda warm the boot will just slip right off the wire

yeah do plugs in wires first. just had that problem.

323steel36

Check this out. The wire fconnected from the opti to the igntion coil had two slitts. It was not fully slit, but could this be a problem

95chevyz28

its possible. I would definetely change that wire out.
