96ss missing :confused:
Ive run out of ideas as to what it could be. I have a 96 camaro ss 6spd man. trans. The car revs up with no problems all the way to red line no miss, doesnt even matter if its hot or cold. But as soon as you put it in gear it starts poping and missing all over the place. Only things iI have done to the car are as follows
-Long tube headers -3inch y pipe -totl slp exhaust -pulleys crank & alternater -fuel press. reg. set at 40psi -pcm 4less tune -msd wires new less than 100 miles -ac delco opti spark new less than 100 miles -ngk plugs set at .50 |
Are you getting an SES light? If so, what code is being thrown? Does the miss show up in every gear at all RPMs?
|
i would check to make sure you dont have an exhaust leak, check your oxygen sensors, fuel pressure. just go over and check everything you possibly can.
I hate to see other SS's suffer. good luck |
no codes or exhaust leaks o2 sensors are good as well,but i do notice it breaks up real bad in 1st gear the most
|
do you have a cable to run data master?
|
BAD GAS.
Maybe just maybe...try putting in some fresh 93 octane gas. |
spark plug wires, under load it would develop and would go away out of gear
|
I never thought about bad gas but than again shouldnt it do it all the time? & no Data master cable either.

i have a brand new set of msd's that i can't use (went to a ltcc conversion) they have 2 hours of use on them if that. pay shipping and 20 bucks and i'll send them to ya.

Sounds familiar. Check your #5 and #6 plug boots, since they're REAL close to the header tubes.
|
I've gotten a bad set of MSD's out of the box, so it's definately worth double checking...
|
make sure their all the way on the opti.

Is the PCM/tune still OBD-II? If so, you should be getting a flashing SES light for the misfires. The PCM will also "count" the misfires by individual cylinders, and that data can be pulled with a scanner with "GM enhanced parameters". Knowing which cylinders are missing might point you in the correct direction.
