Re: cold EA engine troubles!?!?!?

not if its tuned and running properly it wont. why do you think it would be normal that an engine backfires? do you actually think CFI cars did this when they were new?

Re: cold EA engine troubles!?!?!?

oh dear your CFi unit is totally ruined, you need to convert to multi point to fix the trouble

nah joking, but seriously, CFi isnt a good setup. you will notice imporved fuel economy, more power and throttle response after converting to multi point. also at only around 300 complete (if you can do the work yourself) its one of the best bang for your buck mods you can do to the falcon 6.

Re: cold EA engine troubles!?!?!?

Put the pipe back on until you can get a decent manifold in there.

Don't take any notice of all the MPFI conversion addicts on here (even though there may be some merit in their arguements).

If your CFI EA is in good tune, it'll run well, it won't backfire when cold, play up or anything like that.
It'll be reasonably economical ('economy' is in the right foot of the driver of course) and it'll out perform any old Toyota Corolla or Nissan 120Y any day of the week (It might even see off Geminis and Sunbirds)

Not having the stove pipe fitted just means it'll take a little longer to warm up.. nothing more, and that's assuming the diverter valve in the air cleaner is working anyway.

Try all the basic things first.. plugs, leads, dist cap, rotor, air filter, no loose bolts on the inlet system, no loose vac hoses, PCV system is intact, timing is right, etc..
An oil and filter change won't hurt either and don't forget to wash it and clean out the interior. A clean car always performs better than a dirty car (go figure!)

Your problem could be simple or it might be one of a number of things such as (but not limited to) ign module or coil on the way out (not unknown on 'E' series Falcons), MAP sensor, oxy sensor, dirty injectors, a dodgy connection somewhere (earth lead to engine?) or whatever..

But get the basics in order first then you can look for something deeper if you still have a problem.
Find a local garage that can read stored fault codes if still have problems or do a search on this site or fordmods on how to read codes, if you feel you're up to it.

And so it bloody well should!

just saying that the MPi is a better setup thats all. much better for later performance mods is he is that way inclined.


CFi does have an advantage though..... it IS a much better manifold for straight gas setups so ive been told.
