I have seen engines that gave the same symptoms as this and the compression test showed some problems.



At speed centrifugal force keeps seals planted to the wall a bit better. If compression is good then check the injectors. It is less of a pain to check compression than to check injectors IMO.

I know what your saying, but i just don't agree on using the blown motor statement for everything. If its a fuel smoke and hard starting, i would say leaky injector bottom line. But your right, check compression first because its easier just to clear that out. But i would say fuel issue.



A little shaking on any motor is normal, im talking violently or out of the normal.

matt says he ordered a dist. cap from the parts store bc i mentioned that that could be the problem last night, causing a weak spark





also could this be caused by a bad fuel filter?

I doubt it, a clogged fuel filter would result in a weaker fuel flow in most cases. I'd say not enough spark to get the motor going at first, or just a leaky injector that when it sits, fuel gets dripped into the motor resulting in fouling the plugs a little bit causing hard starting. You can try the new dizzy first though, could always use a new one anyway

havent changed the fuel filter since ive had the car, ive put maybe 15k miles on it...



but i dont know how old it is, it was on the car when i bought it, i just need to put the new fuel filter on, do a compression check and all that.



holds idle beautifully, runs better and stronger then ever, engine has just a slight shake when i rev her hard but nothing noticible during driving, you cant feel it when it runs, but you can see it with the hood popped and revving hard.



im thinking it may be the injectors.



a small puff of smoke and it smells like gas, im hoping for the best and expecting the worst https://www.nopistons.com/forums/pub...closedeyes.gif

your motor mounts might be aging man, but im talking about at idle, the motor shaking violently. My motor moves a little to, nothing to worry about really. I'd say its the injectors i bet they are still stock and never have been touched. Prob dripping like crazy

checked the compressrion with trammell tonight, all is well, its the injectors.

so what was the compression for shits and giggles?

nopistons94 05-15-2005 12:39 AM

glad to hear, thats why I don't always rush right into blown motor

Yah people are quick to say bad motor, N/A rotaries are pretty tuff, 12A rotaries are just about bulletproof! Throw a turbo and a bad tune on a rotary and its toast but thats the same for any motor.
