I know this has most likely been posted before but I need some info quick. When I was on the highway tonight going 80 in 5th at 4,500 rpm something weird happened. The engine jumped or something and jerked the whole car. I kept on driving like it was nothing, then 5 minutes later it did it again. Does anyone know why this is happening. Does it have something to do with the ignition or the injectors? Any information would be appreciated.

 

could be your altornador could been your fuel pump, fuel rail, injectors, fuel stranner, fuel filter could be dirtty, that has happened to me as well and i replaced all of these parts and it never did it again, but i thought i needed to replace them anyways..

 

i just installed 440 rc injectors on my stock b20 and it stutters at 4.5 and up..
wat have u done to ur car i might be able to help
