I have an 87 GN motor I transplanted into my 91 Firebird. I pulled it out of storage about a month ago. It has been in storage for over a year now. Initially, the car ran fine at idle and on the road. It was only recently when I took it out that I noticed the idle was rougher sounding than normal. When I took it out on the road and would give it any throttle, it would miss and sputter a bit. Not enough where it would fall on its face, but it's not running right. Some background on the car:
-Walbro 340 w/ Hotwire Kit
-Accufab 65mm Throttle Body / Plenum w/ RJC Powerplate
-72lb Seimens Injectors
-LS1 Maf w/ Translator +
-Extender Extreme Chip from FullThrottleSpeed.com
-GT6776s
-212/212 Roller
-Ported/Polished stock heads
If you need anymore info, let me know.
My scanmaster #s after the car warmed up @ idle:
02 Multivolts - 650-750 range
AF - 02
Ats - 83
L8 - 32
Clt - 172
bAt - 13.9
Int - 126
bL - 136
Ats - 85
TPS - .46
IAC - 70
MAL - 0
My iac and tps seemed high. Any other numbers stand out to you guys?
I did a resistance test on my coil pack (Car cold - 1-4, 3-6, 2-5), with the key turned on (not started - not sure if that matters) and each time it read 8.14ohms. (set to 20K). I believe it's supposed to be in-between 11-13K.
Any ideas? I'm going to try and pull my plugs soon and check to see how they look as well. I'll report back when I see how those look.
Thanks in advance!
