problem whit missfires ???

[BAD BIRD]

ok i replace wires and spark plugs
if i hit 90mph at 4th gear no missfire
but if i step on the gas and i hit the same 90mph
now at 3rd gear the car trows me a ses light
(multiple random missfire)

does anyone has have the same problem??
im thinking maybe the coils ar bad ???
what should i do ??? [img]graemlins/stickpoke.gif[/img]

At what RPM do you misfire and does it happen in any other gear at different speeds?

Are you sure its not just the rev limiter kicking in?

[BAD BIRD]

it happens only at full trotle on 3rd gear at 90mph the rpm is like 4000
if i hit 90mph on 4rd gear i dont get SES light

it is very weird
i took it to the dealler ship ad they said it was the plugs and wires. so i replace both

im going to replace the coils
is there a place on the net where i can get theme????

[terminaldegree]

just about any parts store will have coil packs for this car in stock-- why bother ordering from the net unless you're getting something really esoteric?

Could be the speed limiter. Should kick in at 97 mph if it's not tuned (assuming you had 3.08s before).

but will that cause the SES light code multiple random missfire

The same thing happens to me if I don't use 92/93 octane. Don't know why.

Is it just 3rd at high rpms or every gear? Injectors or coils if not the limiter?
