im still having probs with the el.

thing shudders a tiny bit going from 10k's to 0 and first thing in the morning it stutters and i dont get full power out of the engine.

just before it happened i may have run the tank pritty low. i'd replaced the fuel filter 6 months before, but my question is, if i had clogged injectors or fuel filter would it still be a problem when it got hot? it only stutters for 5 seconds after the engine has just been started. then its fine till i decelerate

do you usually run your tank low or was this a 1 off??? if it was a 1 off it would mostlikely picked up alot dirt from the bottom on the tank and would have clogged the fuel filter again.

the fuel pump might be struggling to pump fuel through the fuel filter on inital start up so the car might stutter untill the proper fuel pressure builds up in the rail.


hope this helps

replaced the filter and it runs a fair bit better now. i think the injectors got a bit of s**t too.

i only ran it dry the once, dont plan to do it again

anyone know how much roughly to clean them?

im thinking one of the cylinders isn't getting enough fuel or something because the engine is still missing at low rpm but when you push it a bit it goes fine. all the sparkplugs look great except #5 but i might have dragged some s**t on it taking it out.

im thinking the problem would still be there if not get worse if the engine is hot? but it seems to clear up a bit after it gets warm.

anyone know how much roughly to clean them?

approx $120 to have the full injector clean done with ur local mechanic, take about half hour and trust me, if they needed it then you can definately tell the difference. i got mine done just after i bought it, cost me $80 cos i got it done where i work :P

In the fuel tank you have your pump, on the pick up to the pump is a gauze style fuel filter, then you have your major fuel filter, so id change your major fuel filter first, see how that goes, then if all fails THEN do injectors, if that fails get a new gauze filter for the pump.

Sucks to be you guys i get my injectors done for free at tafe, and also free dyno.
