My car is running really rich, solutions?

My car is running really rich, solutions?
just got a 94 gt and the thing runs ungodly rich. it has headers and offroad h pipe. im thinking the car is on the stock tune and the computer is thinking its running lean because of the added airflow and causing it to dump more fuel. does that sound about right to you guys? i know a guy who has HP Tuners and will tune it with a wideband for 100$. im hopeing that will solve the problem. the car really smokes alot and im thinking it is because of the rich condtion. the smoke is a grey color, i though when i ran rich it was supposed to smoke black?
i dont know but you can really smell the gas so there is no doubt its running rich. Another question, can they increase the timeing when they are tuning it or do you do that seperately? sorry dont know alot about these engines. and help yall can give me is greatly appreciated.

then you need to find the SPOUT connector, it is a harness that has a grey or black plug in the end. for your car...it's kind of near the airbox, maybe behind it...i forget exactly...but i know it's near the airbox
the car should be warmed up and running....pull the SPOUT out , then loosen the holddown nut at the dizzy base, then adjust the timing to about 12* if you use 87-89 octane 14* might work if your always on premium
the timing marks go from 10-0 atdc and then 0-20 btdc
the way you wanna go is the btdc area.
after you get it on tighten the holdown , recheck it cuz slight movement can change 1-2* easily
if it's good after you tighten it....put the SPOUT back in (the car will idle better instantly as to when you removed it)
and your done.
if the car stalls when you pull the SPOUT out....you have vac issues to fix b4 you do anything

basically you can mark some key timing points 0*, 10* 15*, and your spout is behind the airbox but infront of the strut tower, after timing is adjusted i would recomend driving it around the block and listen for pinging, if the engine is pinging, reduce timing

thanks guys. id say the timing marks are on the harmonic balancer. my dad knows all about that old school crap. i didnt know thats the way you set the timing, sure makes things alot easier. im used to my ls1 so i figured this would be similar, thanks for the help.

jrt1990..... the balancer has a bunch of marks on it, each line is 2* increment
it will be all rusty and not readable from the top w/ a timing light. but w/ the car off...rub a bunch of chalk all over the lines and numbers, then wipe it off...the chalk will stay in the grroves and lite up nice when you you get back up top.
what works really good is grease pencil, yellow or white and will stay for about a year or more. white out or a paint pen works too....bu tthe line will be phat and actually take up the area of almsot 3* so not as accurate if your being picky.
gtpcoupe...you can get away w/ a shorter 1/2" wrench...but it sux, and w/ the car running your always getting your sleeve into the belt or something stupid.
that dizzy wrench is trull worth it's weight in gold.
i like nitrous so i change my timing about 5 times a week in the summer so maybe more so for me.
even no nitrous...you can take advantage of 2* here and there depending on temps and humidity
cool dense air can take 2-4* more than when it's hot and humid outside.
and sometimes every bit counts
like stated...if you skip the SPOUT part....the timing will not take...it must be removed b4 you change it, and it then put back in when your done. if you forget to put it in, it will not advance at all when your driving...and you will lose almost 50 hp
i know cuz i lost it once at the track...was running 1/2 sec slower for 3 runs, got pi$$ed and rechecked my timing , saw it was gone and borrowed my buddys in between runs
i used to put it on the batery when i was changing it....just forgot it and it must have fallen off
picked it all back up as soon i put his in, now i have about 5 spares in my toolbox...if your in a boneyard, they are in all fords w/ 302's pickups stangs everything
