I have recently bought a 1993/4 sti type RA. The problem i have is when im on light throttle i have hesitation/spluttering but once you raise the revs slightly it clears?

i have done new plugs and service today. The car is standard as far as i know bar an airfilter

thanks

I would check the fuelling side of things. Fuel pump, injectors etc.

is there a common fault to look for? and do you know the resistance i should expect from the fuel pump and injectors?

I'm not sure on resistance but I would eliminate the obvious things first. If the fuel pump is the original it may be a little tired. Likewise the injectors may need a clean.

yeah my plan was to get the injectors out and give them a clean are they easy to remove? and are the RA fuel pumps the same as normal STI's?

Also would a tired fuel cause me starting problems when its cold?

I know your going to laugh but i have the same problem when the air-con is on if off nothing !!!

ellodave

air con dont work on mine so that rules that one out for me lol

Injector removal is fairly straightforward. The fuel pump is the same in the STI/RA AFAIK. Try posting in the general technical section, you might get some more pointers in there.
