Question Burning EYEs!!!!!

OK i had a little problem last night i was blowing the cob webs out when all of a sudden my car went DEAD RICH.........and started bogging soooo i limped home and today i changed out the Fuel Regulator and took it for a short run same thing it went rich and started bogging out......So my question is..
DO YOU THINK IT COULD BE MY IGNITION OPTI SPARK OR MODULE OR COIL??? when i try to rev the car it just sputters and bogs down but there is no back fire so i'm turning to the LT Crowd. Any input will be greatly appreciated........

does it always run bad? or after it runs it does this? if it runs ok on inital start up it may be the o2 sensor showing lean all the time. no correction in open loop

if its burning your eyes and you "think" its rich... its most likely lean. its a common mistake made, you smell fuel and think o rich, when in reality its so lean its dumping fuel to try and catch up. unless you have a wideband on it to see what its actually doing.

yea, or just starting it for the first time in months, since cobwebs typically take a few weeks to form, depending on your infestation of spiders.

I would say call an exterminator...it is the cobwebs that your worried about..right?

You need to do diag, check how hot your spark is and what your fuel pressure is. If you have live data stream this would be the best, go for a drive and see exactly what is going on. I can guess all day what is causeing this issue. doing proper diag will save you lots of time and . I bet the MAF is dirty

Before my last tune, my car would burn your eyes and stink of gas just idleing... so bad it was like you were being hit with pepper spray.

Thought it was running mad rich until we threw her on the dyno and started tunning... it was retarded lean everywhere, so bad that the tuner said "holy ****" really loud.

Dont assume it to be rich.

Other than that, I have nothing else to contribute here.
