RUNNING stupid rich, started out of blue (93 FD) mod list in sig
93 FD
I walk into blockbuster, after driving my car there, which was driving fine at the time, come back out and it has a loping idle...nothing was done, nothing could have been adjusted or knocked out of place.
I have adjusted the valve under the throttle elbow, i have adjusted the TPS, checked the ICS mechanism, nothing seems to be wrong...
Symptoms now are at cold startup, it idles at 1200 rpms but a lil rough, sounds like its running rich (popping and whatnot).
by the time it warms up it lopes from 1500-2000, the smell of fuel is rediculous. It drives fine, sounds like it is running very rich (lots of backfiring and popping) but it drives.
I guess the #1 sign of trouble is that it is running rich all of the sudden and i dont know what caused it...the idle may or may not be connected to that
This type of problem has happened before out of nowhere as well but tps/valve under throttle body fixed it those times, not this time however.
ANY help would be appreciated, although i fear it will come down to tuning, although it doesnt make sense that it would start out of nowhere. IS there a sensor i am missing??? could this be fuel related?!
I AM RUNNING STRAIGHT PIPE RIGHT NOW AS TO NOT DESTROY MY CAT...however my car was tuned by XS engineering with a straight midpipe...also i had a walbro fuel pump when it was tuned, currently have a skyline pump, i know it's output is higher but it ran fine with it for several months.
