Cold start injector got stuck open?
i was driving around in my ta22 when gradually my engine started to flood, now she wont run without flooding, what are the possible things that may have broken.

there arent to many things that will cause an EFI car to "flood." i would also suggest cold start injector.
Also, your pressure regulator could have become stuck closed, causing maximum rail pressure. that would cause extra fuel to go in the cylinder when teh injectors are opened.
factory management or aftermarket?

thanks for the help

ok injectors now rebuilt, they were very blocked. still having the same richness problem though. is it possible that it was broken and now its fixed it self so its working good but my maps are wrong??
thanks and laterdays

Did you have the cold start injector checked?
it could be possible that the pulse time on your map is all wrong. you say that cylinder 1 seems to be ok, but the others are no good. check the pulse times on your map to ensure that the other 3 cylinders arent pulsing for too long. this would give a rich mixture.
if there is a difference between no. 1 and the others, then you know something isnt right there....

i will try to make a semi drivable map to get my car down to underwood, hopefully when it gets tuned it will all sort it self out.
