injector help?? ka24de

[Axel Grungy]

ok im pretty sure this is an injector problem. every once in awhile my car likes to run on three cylinders (IE motor shaking, sounds like harley) when i start it up. im getting spark on all cylinders cuz i pulled out the wires one by one.l ive narrowed it down to the #1 cylinder. btw i havent pulled out the spark plug yet to see if its fouled or not, but i would guess once its fouled it will not work at all. so im pretty much ruling out the spark plug as the prob, but i will check it tomorrow (new ngk's were put in under 1k ago). ive also checked around the injector to see if theres any gas leaking from the O ring and tahts negative. so my question is how do i make sure the injector is working?? btw ive cleaned the contacts on the injector plug also. but im pretty much stumped, this prob comes and goes.....any ideas would be appreciated.

it might just be clogged, try seeing if some seafoam in the gastank would help (whats 5 bucks gonna hurt anyways, and it gives you a reaosn to run some through the vac line anyways)

good good, yeah i was having a feeling it might be clogged. ive carbon cleaned the engine with seafoam but never got around to putting it in the gas, and vac hose. any other ideas??
