I have an 87 T with the normal fuel system upgrades including 42.5 injectors and one of Eric's street chips. I just had to put a new cam in the car (Comp Cams 212/212) because problems at the #3 cylinder. At this time, I installed Eric's chip.
I am getting no knock at WOT - which is good. However, my numbers at idle are as follows:
AF 05
L8 36
INT 128
BL 141
ATS 134
TPS .42
IAC 19
At WOT my O2 numbers are somewhere around 820 -sometimes a little higher and sometimes a little lower (never under 800 and never over 850)
The O2's do not jump around very much at idle. Cross counts do not move at all at idle. I installed a heated O2 sensor in January and have probably only run about 10 gallons of a race fuel mix (5 gallons leaded 114 and the rest 93 pump unleaded) through it since installation.
Fuel pressure is set at 43# line off.
Questions:
1. Is my O2 senor bad already? If so, is this normal for one to last such a short time? I have a friend who runs straight C16 and has not replaced his in two years.
2. The BLM is too high. It should be around 128, correct? Is this related to the O2 sensor issue?
3. What do the other numbers look like?
4. What adjustments do I need to make?
5. Eric, if you are viewing this, do I need to make any adjustments to the chip?
Thanks as I am still learning.
