97 Explorer sport EFI
Okay fellow Ford owners,
I need your help before I waste a lot of money here. My used 97 explorer sport with EFI engine(165hp) with 91k on the odo tends to shut off on me whenever I floor it or come to a sudden stop while my A/C is on. Okay, I was told that its my PCV valve, that it needs changing. Also, I was told that its my compressor wheel...that I need to have the dealer inject some lubricate in. Now, I'm not sure what the hell to think here guys. I was just gonna head to the nearest dealer here and explain to them whati just told you guys. But hopefully I can get some valueble info that can help me out.
I tried to look for this question on this board(so you wouldn't have to answer over & over again) but I didnt find it.

Compressor is internally lubricated. If the previous owner ever had it refilled, it might need lubrication added. If it is stalling your engine because it needs lubrication, you need a new compressor. The idle air control valve may be sticking and needs to be cleaned or replaced. Other than that it may be a vacuum leak in a hose, air horn, or loose clamps. The other bad news is that it may be a leaking lower intake manifold gasket. They will replace PCV but doubt that will do anything.
Also, since you are getting at that magic age, check the spring belt tensioner on the left side of the engine. There is a little white plastic bushing betwen the arm and the part that mounts to the engine. If you see more plastic on one side than the other, the are is about to wear through. This will pop out, cause a lot of damage, and leave you stranded. Just had to rebuild mine on my '97. New part is about $45. Figured the factory design was so bad, I redesigned it instead of buying another one.

Thanks Opera,
I just got an estimate & priced a compressor today...$389. @$89 an hour for labor(I know they're gonna take a t least 4 hrs on it), parts to recharge it, disposal fee, taxes. I know i'm already out of at least $600 easily. I crunk up, turned on my A/C and opened the hood. I think I may need a new compressor like you said because it was making a loud "bearings" sound. I could hear the bearings turning inside. I'm gonna try to relube it first and if that doesn't work...there goes my new tires savings.
