Help!!!

[GN GURU]

Car ran fine I changed spark plug rts44 & put auto lite 23 gapped at 35 and retrofit from r12 to 134 charged the ac system now when I get on the car it breaks out (popping under boost ) any ideas the ac was on maybe that????? Thanks guys

 

[kidglok]

What gap were u running previously?

 

[KevinB]

That's a big gap.

 

[GN GURU]

Close the gap to what I've always ran at 35 gap???

 

[kidglok]

i bet your coil pack/module is on its way out

did you try it with the a/c off?

 

[GN GURU]

No I will try it tomorrow

 

[GN GURU]

How bout the wire ?

 

[GN GURU]

Car was fine till I swap the plugs and fill the ac

 

[KevinB]

How much boost? I ran .024 at 30 psi. Try .030 and see what happens

I'm upset cuz I gotta do the tranny on my other Buick now I'm stuck on this junk lol

 

[GN GURU]

I'm ready to js put a set of rts43 in and see what happens

 

[KevinB]

Well, the 23's are a colder plug than the 44 I think. The colder plug may be the reason the spark is blowing out with the same big gap.. Just a theory.

 

[KevinB]

I would close the gap and see what happens. If it don't work you are out 15 minutes. Worth the try IMO.

 

[GN GURU]

Will try closing 32? 30?

Bison told me to run ac plugs r42 ts with a .028 gap and it's always worked for me with up to about 26# of boost which is the most I ever ran

 

[TurboDave]

Those are awfully cold plugs. Close your gap down to .028 and give it a try.

I use NGK UR4's...no issues gapped at 32. If car ran good before the plug change, probbly pulled a spark plug wire out of the metal connector in the boot.

On cold start up it's fine but 5 to 10 mins in car start to break up when motor warm up???

 

[Royal-T-Ltd]

Bad O2 sensor maybe???? any readings or logs?

Also I know it sounds dumb but verify all the spark plug wire conections are tight and "snapped on" at the plug and coil

No chk eng lite on I have scanmaster
