89 5.0 TPI engine vacuume specs?
My car is not idling right and I replaced damn near everything(TPS, IAC, computer, coolant sensor) Still surges and dies. The only time it runs bad is at idle and when it warms up really well. I think it may just be a worn motor, I checked the vacuume and its at 19HG I was just wondering if thats within spec? Any one have any thought on what it could be? Any help will be MUCH appriciated.

Okay so I put some Prolong in my car and it helped the oil pressure go up to 30 at a good warmed up temp. So now I'm pretty sure its just a worn out motor. Just gonna run it till it dies.
