So my 91 Turbo car has been sitting for a couple months, but needed it as another one the POS's died. Get in, fires right up, runs for a minute, maybe, the check engine light comes on and it starts to run like crap, missing and engine speed slows down enough to kill it.
Check the codes:
13- MAP sensor or vacuum line may not be working
Easy enough, check the vacuum hose and maybe replace the MAP
27- (turbo) injector circuit #2 not switching right
Don't have a clue on this one and more than likely the cause of the running issue.
