Question about Cars & Trucks
Why won't my idle idle at the normal 900 - 1000 rpm when stationary??
Hi try testing your egr valve, that usually happens on Mitsubishi. If is an older model might want to check the CO2 sensor and catalytic converter

Most automatic transmission cars have what's called a "TCC switch". It's a switch by your brake pedal that when activated. It releases pressure in the torque converter, so when you come to a stop, it let's your engine turn more free, (torque converter clutch. Check fuses, that switch, and all connections to the transmission.

SOURCE: slow acceleration, high rpm
This sounds normal to me! The engine will read that rpm when accerlerating lightly. It is the stall of the torque convertor. The oil pressure will always be higher when the rpm's are higher, or when the oil is thicker - cold.
Virbration? That is a different story. Oil won't cause that.

Add a can of SEAFOAM to gas. Replace fuel filter(will have goop in it). replace fuel filter before next 500 miles. Add SEAFOAM every 3000 miles after that, and that should fix 99% of the problem. good luck.

sounds like vehicle may have a vacuum leak somewhere. u can try to spray some throttle body cleaner around top of engine area around black plastic and see if rpm changes or engine stalls.
egr valve could be sticking. (exhaust gas recirculation) typically this would turn on a check engine light but not always. no easy fix/diag here requires scan tool and replacement if bad.

Testimonial: "Okay! Willing to give it a try."
sorry but you have tried everything i would have done except that i would have checked the engine breather pipes for deterioation like perished or soft and collapsing .you would be surprised how often this is the main cause of this sort of problem
