Hey all, I've got a 1991 Cutlass Supreme 3.1 [T engine] with the 4T40 trans. I've had the car since my dad passed in '95, and it only has around 90K, with just a few parking lot 'dings'. Overall, it's been a great car...until last year. I'll be looking, and posting, hoping to find some tips/suggestions on how to figure out what's wrong/what to test, etc.--'cause the OBDI just doesn't set any codes to help. I have the original GM manuals for the car [3 vol. set], but there's just TMI:confused: in them without enough specific scenarios that match my current issue! Here's hoping y'all can give me some pointers.

Whats Up?

 

Probably out of blinker fluid or the plenum needs re-aligned, either of these two problems will not set a code. But yeah start a thread when you get a chance and give as much info as possible as well as any results from tests you may have done.
