Dead Daily Driver

[Boy Buick85]

Hey guys my T is my daily driver, anyway i was driveing her home when she started to choke and she went real rich and when i would apply throttle it would get worse until she would just die. Anyway idiot lights say oil choke, so i checked the maf wiggled it around a bit, nothing changed, checked the ecm wireing harness, it looked fine then i herd something dont know what something metalic break or come loose. When i let it sit for a bit she will run good for a few feet then start chokeing again, then dies. What do you guys think

Do you have any error codes or scantool numbers?

Yep

YEP EXACTLY WHAT IT WAS. as soon as i checked the MAL code 41 and 34, i unpluged the maf and drove her home. I had to swap the maf off of my 85GN. Will this hinder my performance since this one is a stock MAF :frown: ?????


YOU GUYS ARE GREAT I APPRECIATE ALL THE HELP

I am in the Sugarland area. Maybe this weekend if the weather holds up.

PS:
The callibration of the 87 MAF is different from the HA unit.
So if you upgraded and re-installed the OEM MAF, your chip should "technically" be re-written. I am sure it will run fine, just not "most efficient".

Thats Not Good

Yes mine is an 87 setup. So your not sure if it rewites it, if so what happens when im ready to put an 87 maf back on. will everything be compatable and working right

Let me clarify my comment;
Rewriting the chip is done by your chip writer. The computer (athough it compensates to some extend) will not rewrite the code in the chip.
After you re-install the 87 MAF, all will be back to normal. Normal is defined as "what the chip was written for".

Edit;
I would not chase any BLM and O2 numbers with the "short term/temporary MAF". Leave everything alone and replace the MAF ASAP as the rich condition may create some other issues if ran for longer periods in time.
