i work a advance auto parts and a customer came in, he has an 87 t2 and he wants to sell it. i'm contemplating buying it. however, he said whenever it gets warm. it wont restart and floods he thinks. i have no clue what would do that other than injectors. he claims he had it worked on and the replaced all kinds of seals and stuff. it has 93K original miles. any ideas if it worth 4k ?? its never seen snow and you can eat off of anything on this car. any ideas what would cause that as well? serious problem? i know the s4's have an issue with flooding. but im cnfused

 

compression test.

if the engine is healthy move on to items that tell the the ECU what the engine operating temps are(AFM and water thermosensor).

low fuel volume can also be a problem, like dirty fuel pump sock, weak pump, dirty fuel filter or vapor-locked fuel system. but those are rather uncommon.

 

he had them do one and apparently its great. i think 90 on front and 89 on rear is what it was.

 

The low compression S4 TII engines are the most likely to see flooding problems. It really doesn't take much of a compression drop from brand-new for it to start happening. My engine would do it occasionally with 110 psi compression. The simple fuel cut switch is the cheap work-around. A programmable start fuel map is the real fix.

what you mean fuel cut switch? like run the pump manually with a toggle?

 

Flooded? Flip the switch to turn the pump off. Crank for a few seconds. Turn the pump back on and start it. It's a very common work-around on these cars.

 

ah i see. sounds fairly simple

 

probably wouldn't hurt to have the injectors cleaned and refurbished. at 26 years, perhaps they're leaky.

 

I had such an issue for a long time. My problem was a bad BAC-connector. The ecu sends a signal to the BAC which opens it 100% at each hot start which helps a lot. My BAC didn't get that signal and because of that the engine was getting too much fuel while starting. As the others allready wrote bad injectors could cause that problem, too.
