misfire on idle and part throttle 318 F reg

Post Tue May 31, 2005 8:48 am

had a little search but......

got a misfire on idle revs to about 500rpm doesnt stall though. is abit lumpy on slight throttle its the same but when on more throttle and booting it it seems fine smells fuelly thought. on this basis i thought it would be a vacuum leak causing it to run rich as bugger what you all think?

oh and when first started revs all over the place for a few seconds

vacuum leaks on the s13 always made it run rich?

mine jerks a bit on part throttle, did it lots when low on fuel, and then started to pop big flames aswell when on part throttle... dont know if it was to do with my fuel pump problem i had the other week.
