Trying to assist a local friend . . .
The car failed twice and not sure what to do next. (See attached pic for test results)
Last year, with the same setup, the car passed.
Other than chip and FP, nothing was changed.The car get driven about 1000 miles/year.
We installed the TT emissions chip, lowered FP to 37, got it up to +190F on a stretch of highway and dove it to the test station.
Car runs on straight 93.
The car is a +95% stock 89 TTA, 31K miles.
Here are the mods;
-AFPR
-Blue top injectors with matching TT Emissions chip
-Upgraded fuel pump.
-Valve cover breathers (2)
-Plug wires
(I think that is about it)
Here is a list of maintenance related items, that I am aware of;
-Car runs fine, and O2 sensor appears to be a a purple wire Delco.
-Plugs and wires appear to be ok (???) Car runs fine, no issues.
-TPS / IAC / LV / CC / all look good.
-Idle BLM is around 136 (idle cell), but once on the gas, the next BLM cell is right around 128.
-CAT is new original replacement with less than 3K miles
-The only thing I did not like was the MAF reading of 4@775 rpm (Park).
I will perform the EGR test tomorrow.
Any feedback is appreciated.
