CFI Injectors and other questions

1. Can you get better injectors for cfi's and if so do the give any performance gains.

2. Also my car seems to be running rich, back of the car gets black soot all over it which is a real pain to get off especially if you own a white car. Any ideas what is wrong, might be the oxy sensor but im not sure, should i just go get it checked out and serviced or try and work it out myself.

3. i bought a cheap after market tacho and ive searched all over for info how to install it but i cant find any if anyone can give me simple instructions how to install it. I know its got a wire for earth, +, - , coil but where do you attach them.

4. Where is the main earth wire located on the body of EB's

5. The car also revvs heaps sometimes, i know the isc is pushing the throttle open, can you just simply replace the isc to fix the problem.


Sorry about all the questions but this is about the only place i can get some good informative answers. You guys seem to know what your talking about and because im young i dont want to be ripped off by auto places telling me i need things i dont.


PS. I have a 5spd CFI EB and live in Canberra, so if theres ever another canberra cruise count me in :)

Dude, im not familiar with the CFI setup, bit I reckon its pointless chasing errors and stuff with it.........spend the money you would to fix it and go buy a MPI setup. You could bolt it all up yourself, the only hard part is the wiring but there are at least 5 guys on here who have done it.......food for thought?

As for the running rich, check all the 02 sensor, thermostat and timing. I personally found my car ran rich due to a rooted dissy rotor, the timing was shot, plugs and leads were starting to show their age.

There are a few things that account for high idle. Power steering switch- unplug it and short it out, hight coolant temp, or a faulty isc. The isc has a spring loaded switch in it on the spindle to sense if the throttle is resting on it. When the throttle rests on it it knows its meant to idle and then starts to lower the revs to idle. As soon as you touch the accelerator you will see it jump up a bit to where it stays until the throttle hits it again. Dont spray any crc down the spindle or you will wash crap into the switch and the motor brushes.
