Not likely, it would run rather rich, due to bad ignition timing. My 93 recording got a code 36 in it and it was a new bad opti! It only shows BLM and INT values on the rich side, even though it just has been tuned with LT4 hotcam. I personally prefer to look at the adl files with moving numbers, oh well. You sure got a major lean issue! Get yourself a smoker, close the exhaust and throttle body with tape and let him blow the smoke in with a straw, free at McDonalds ;-). The computer is for sure dumping a lot of fuel in (high inj pulse width numbers)to make up for the lean condition, but cannot get a handle on things. To much fuel robs you power, just like to little. BTW your IAC values seem to confirm the false air issue. Permanently low values and at idle closing altogether, not good! Unfortunately TPrt always gets some spikes in the recordings. For a split second almost all values max out, when it makes no sense. You'll learn to ignore this real soon. Don't forget, TP is a one man show for free, with a lot of support from the 3rd Gen guys to get a handle on things. No commercial interest behind the movement. The guy sure isn't gonna get rich from the voluntary support! |
