help please.....fuel....i think??? ok the problem: my car sputters when accelerating. seems like a horrid miss fire. but it stinks like gas and spits out a little smoke. can only get it to screw up on me when driving down the road.....cant get it to do it in driveway.
i think im getting too much fuel??? everything is untouched w/ the exception of new vaccuum hose on the fuel pressure regulator. i got the smallest stuff that the parts store had, ie...1/4". i do not have a gauge to check the pressure with so im kinda stuck. does anyone have any experience w/this issue?

Did it happen right after putting the new hose on the regulator? That wouldn't change the PSI unless the regulator is messed up. Find a fuel pressure tester and put it on your windshield while you drive. I would check plugs and inspect all the wires. No codes?

yes threw code. dont have a way of checking it. well i have a paper clip...but i cant get the light to blink like its supposed to???
yes and no. it initially started this a long time ago. but it was very rare...and i could put car in neutral and rap it out ie...5700 rpms...and she would clear out and run like a champ.
oh yea when it is doing this "sputtering" if i can keep my foot in it long enough....it clears out at higher rpms....thats another reason im leaning towards too much fuel...

You can't use a paper clip to check the codes. That was a `93 thing. Go to advance auto parts and get it scanned, I think it's free. So find out the code and that will narrow down the possibilities.

Sputtering at lower RPM's, smelling unburnt fuel, cleans out at high RPM's = sounds just like a plug wire issue. Check all your wires, make sure none of them have fallen off the opti or the plugs. Make sure they are all nice and tight. When's the last time you changed plugs and wires? If they are all tight, pop the hood in a dark area, look from the top and bottom on both banks, see if you can see any of the wires arching.

ok. nothing on the headers....all tight.
but...saw a little light coming from the coil wire. near the boot at the coil. it actually looks as if it has been touching my water hose and arc-ing across there. so being brave....i reached down and touched the wire!! lol nothing bad happened....but it was lighting up around my finger where i was making contact with the wire. you know....kinda like one of those lil ***** you can put your hand on and all the electricity goes to your hand?? so i have a spare coil wire layin around...i will try that right now.

ok. spare coil wire....cracked. no good. finally found the trash. lol
put some elec. tape around current wire and added fiberglass sleeve. zip tied wire away from coolant hose. still arc-ing through.
and got my car to a darker place....looks like there may also be a cracked plug...as i can see some light coming from the base of the plug/boot on the #3 cylinder.
also....it looks like i can see the coil itself arc-ing??? just like a wire would. little white glow. but its the whole unit itself??? it is an accel piece that i bought from a local f-body guy. (not a sponsor so no name) maybe i need to replace coil, wires, plugs??? but damnit i dont wanna spend money troubleshooting anymore....this **** gets old!!!!
