I have a stock 91 crx si and at random times while im driving my car the rpm needle will start moving up and down all crazy and the car starts to get this jumpy feeling. After that happens sometimes (hasn't happen since i got oil changed about 2 weeks ago) my car will just shut off while im driving or at a stop and it wont start back up and ill wait like 10 min or so and it starts up fine. If anyone out there could help a brother out I would grealty appreciate it. Thx

 

check all the basics like fuel and spark... check plug gap and condition of plugs and wires... i always recommend ppl check that first . you have and engine lights?

 

engine lights?

 

sounds like plugs n wire to me = )

easy fix

 

I would start with wiggling wires while your car is at idle, like grounds and ignition wires.

 

sounds like a IAC valve to me

 

if the oil was low before you changed it that could have a lot to do with it....

 

and it was too...thats weird
