Engine missing questiong

[DDot690]

I have a question maybe some one can help with, I just swapped the intercooler/turbo & Injectors on my car. The injectors are Motorons 60/65 and a chip from Eric. Car run pretty good at full throttle but it idles like crap and seems to be run very rich. I have tried several different fuel pressures with same result. I swapped the O2 sensor with a Denzo O2 and it still missing. I changed the spark pulls and it cleared up till I did a WOT run and now missing again. I assume on or more of the spark plugs is fouled out now. The scanmaster reads at idle: O2 761
AF 05
L8 34
BAT 13.1
INT 128
BL 131
CLT 185
ATS 120
RPM 850
TPS .44
IAC 30
MAL 00

I will most likely take it to one of the local buick shops this coming week but would still like some input from the Forum if you have any ideas.. Thanks

How old are your

plug wires?

Check to see that you don't have an inj. wire pinched or grounded out.
