stony Posted April 30, 2003 Share Posted April 30, 2003 Ok need some opinions. car idles kinda rough and sounds like its missing a cylinder or tune under acceleration. pulled checked all the wires and made sure i was getting spark...trust me im getting spark i think i have a stutter now i pulled all the plugs a had a look ... 2 of the 6 have white tips and the others look fine. these are brand new hks racing plugs so they shouldnt be the problem. Initial guess is the injectors are clogged on those 2 cylinders causing them to go lean under load. any other suggestions before i pull them and get them checked?

ZR8ED Posted May 2, 2003 Share Posted May 2, 2003 This may sound silly, but have you adjusted/checked the valves?.. or are they hydrallic? (sp?) Just an idea...recheck the timing if you do have valves that need adjustment. Good luck. Quote Link to comment Share on other sites More sharing options...
stony Posted May 2, 2003 Author Share Posted May 2, 2003 Its fixed . i took the injectors to be flow checked they all flowed 67ml they gave me new orings and screens.. I installed them and now it runs great. the only thing i can think is the fuel dried up in the injector over the winter and gummed up the screens impeding the flow of fuel. so problem solved now to organize teh rats nest of wires under the dash Quote Link to comment Share on other sites More sharing options...
clint78z Posted May 2, 2003 Share Posted May 2, 2003 More than likely the injector was not closeing properly leaking at idle, it causes rough idle and harder starts. My brother talon did this, it also would bleed down the fuel pressure on the guage after the car was shut off. Good to hear it was cheap !!

stony Posted May 2, 2003 Author Share Posted May 2, 2003 nope it was screen in the injector not allowing theh fluid to flow thru the injector. this is why when the screen s were pulled and the injectors flow checked everything was fine. after the new screens where installed the car ran great;> what i think happened was the car sat for 6 months or so and the fuel in the injectors evaporated leaving behind a film that harded and wala restriction Quote Link to comment Share on other sites More sharing options...

clint78z Posted May 2, 2003 Share Posted May 2, 2003 My first startup this summer I had a poor idle, simular situation. A loud ticking from one injector. Which ticked me off it was brand new, I took it for a drive down a bumpy dirt road and it ran normal again. Good luck at the strip. Quote Link to comment Share on other sites More sharing options...
