stock b17 with bolt ons.
recently i did a tune up and ran fine.
but about 2 weeksafter that. it started running very bad. its almost like it was only running on 3 pistons. its like the firing order had messed up. also the RPM's seem to "play around" and go up and downn randomly.
- it only does it from 2k-4k RPM's when im regularly driving. uses 93 octane. i cheked for bad vacuum lines, idle, throttle, fuel lines*. and CANNOT find why.

anything would be helpful as this is my daily driver. thanks


******would be any good if i SEA FOAM the car?

 

still bad...any help

 

did u check your spark plugs, wires, maybe even dizzy?

 

If your firing order is off, you will notice that @ start up everytime...IE the car stutters real bad...I had that prob when doing my dizzy on my B16, figured out the order and VOILA...Good to go...As far as your idle is concerened...Trie loosening the screw on the throttle body, I did this to help keep my idle stabilized...Good Luck...

 

yes, my iddle is good now. thanks. but still having that problem im going to check and replace dist.
-btw did you get your dist. from a dealership or online??? web?
