So i have a 90 N/A fc at 150xxx miles, well i was driving then i came to a stop sign car started jumping from 0-1rmp like if it was going to turn off but it wouldnt.. Got home car was still doing the same, exhaust was throwing alot of smoke weird :[ never had that problem till now.. Anyone out there know wats up?

 

What color is the smoke and what does it smell like? You might want to do a compression test.

 

Update: so i let the car sit there nd hours later i go back out put the key in turnd it on nd it started normal idled normal too.

-go48 : smoke was darkish grey nd smelled irony lol it doesnt usually do that neither does it blow out smoke like that. Weird how it boobled nd needle jumpd beetween 0-1rpm

 

the rpm jumping could be from a bad/un-adjusted tps. search for the test procedures if this happens again.
