Ok guys I need some help finding out why my car is missfiring....
I have a CEL for missfire in all of the cyl.....
Also When idleing it idles high, then sometimes drops really low..
When driving sometimes under accel it sputters and there is almost no power at all..
Occasional lite pop sound from exhaust when at idle.

I have new:
Plugs, Wires, Cap, Rotor, Coil Pack, Distributor and Idle Air Control Motor.
Also replaced the Electric Load Detector with one from a Junk Yard.

Aftermarket mods:
Injen Short Ram, Edelbrock TB, Skunk2 IM, Greddy EVO2, Alum flywheel, ACT clutch, and ZEX wet nitrous system

I have done a compression test and came out ok 150-165 across the board...
A leakdown test showed less than 5% leakdown on all cyl.

I ran a OB2 scan tool and it read a miss on all cyl.
If i would record 60 sec of the car running it would read the missfire and also a High Electric Load Detector Voltage, and sometime would read Low Map Sensor input, and also IAT low input.


Any ideas what might cause all of this would help...For the most part I think that i covered everything that i have tried to fix the problem, but still no luck..

Thanks for the help,

JMAN

FOR ANSWERS

 

lol i like your second post

Well since you did an awesome job of telling us what you replaced all i can think of is make sure your wires are in the correct firing order and your motor has sufficient grounds also.

 

Check your timing too.

LOL...yeah i tried my best to describe what i did already....I quadruple checked the firing order...and the grounds look alright...I took the plugs out today and left them connected to the wire and turned the motor over to see if the spark was firing..and too me it looks really weak.. im going to wait until talk to my dad and see what he thinks about the sparks that it is making..but to me it looks weak...any ideas why this might be..I replaced the distributor about a year ago..and the coil pack about 2 months ago..

Thanks, JMAN

 

Well if its weak im pretty sure the distributor controls that... just because its a year old doesn't mean ****, get it checked out.
