1976 - 2.0
Just got the car back together, new clutch plate, pressure plate, T/O bearing, flywheel, terry cable, bushings and engine re-build...Pedal play is 1/2 to 3/4 inch... When I shift, I get momentary shudder in all gears (more pronounced in 1st, 2nd, lees in 3rd, less in 4th hardly noticeable in 5th) and the car lacks all it's power... Valves are adjusted correctly, F/I seems to be correct, no vacuum leaks that I can find... Any thoughts ??? 2-OH! |

So its the engine that shutters? Or something else?
If its something else, it could be the half shafts.... I know the 944 turbo "shutters" when its under large load. Andrew |

I agree with Mark: check the motor/transmission mounts.
Mine is doing the same thing. When the shudder occurs, the shift lever also 'bounces' around, and the gas pedal seems to push itself in. The first time it happened I thought the car was possessed. (IMG:style_emoticons/default/unsure.gif) I just received some new mounts from JWest Engineering and am planning on replacing the old ones this week. I'll let you know if it fixes things. |

Can you look at the mounts and tell if they are good, bad or indiffererent...While I had the motor out, I cleaned and inspected the mounts...They look good, feel solid, no cracks or disbonding, not oil soaked...They feel solid...
How do you test/check em'... 2-OH! |
