Toyota MR2 Message Board - View Single Post - Engine Stutters in Gear, rough idle aswell

Alright Im going to try and get this all sumarized in the first post hopefully.

When it happened: 24hrs after I finally got the valve stem oils seals replaced, aswell as a well needed tune up. Before these issues arised it ran flawlsly, it was beautiful how smooth the car operated. I have a little under a 1/4 tank of gas. Right now Im poundering a clogged fuel filter, and dying fuel pump.

What does it do:
1. When in gear the tach shoots from 1k to 3k irradically and doesnt correspond to actualy RPMs.
2. When in gear it rides like a angry Bull pumped full of testosterone. When at idle, it does it regular idle bounce which has never caused any problems, but lately the bounce has more of a hesitation to it.
3. Engine only starts 0% of the time since these problems have occured. Ex. You can hear the started click in, but no crank, no other noise.
4. When key is turned to ON position, CHECK ENGINE, BRAKE, and COOLING FAN lights no longer light up. When switched to off cooling fans continue to run, and CHECK ENGINE light stays on but dim until clutch is pushed in.
IT DID THE SAME THING WHEN MY VALVE COVER GASKETS WENT OUT AND DESIDED TO REPLACE VALVE SEALS AND COVER GASKET

What have I done to the car: New Bosch O2 Sensor, new Bosch Dizzy and Rotor, New NGK V-Power Copper Plugs, New Toyota Wires, New Victor-Reinz Valve Stem Oil Seals, New Valve Bucket Shims, New Felpro Valve Cover Gaskets.

Recently fixed issues: I was getting zero compression, this was due to me having the exhaust cam installed wrong, flipped it around and got 130psi across the board. Dizzy was 180* from where it should have been, flipped it around and set my timming to 13* BTDC, and fired right up. I broke off a corroded engine block ground that looked helplessly repaired by last owner, do just for a temp setup ran a wire from chasis bolt to block and noticed no improvement, before or after the problem.

Things Ive checked: There is no oil in the spark plug valley. All connections are tight. No missing vacum hoses.

My personal issuses: To many to list, about 85% are about the car.

Any idea? The one that helps me the most will get a tasty cookie...
