my cars sick

[red92rs]

car seems to be running quite nice now, its been starting right. cept for sometimes it seems like it hesitates when i put it in gear and try leaving in the mornings, or after a day of work, it seems as if its trying to flood itself... its getting gas, if the winds right, i can smell the gas from the exhaust when it does this.. if its a weak spark due to the coil maybe crappin out, it looks like a stock one on there... if i should replace it, should i put another plain one, or get one like an accell super coil with hotter spark
thanx for anyone's everyone's help

Did you check your ign. timing?

[red92rs]

no havnt checked the timing, didnt think of that, cant go check tonight, got storms keepin me from that.. im not sure on which wire im supposed to unhook to check/change the timing... never done it before

[wrightz28]

There's a single wire, normally tan running along the top of the firewall on the passenger side. You'd need a timing light as well, or best case scinerio from the way it sounds, a buddy with a light and a little know how.

weather guys said no more rain after 1 storm moved thru, and several more moved thru. was going to look for that wire and retrofit my ac for the new stuff so i can be cool in this 100+degree temp... whats about the best degree of timing for these engines, or does each engine have a special sweet degree u have to find.

make sure there isn't any R12 left in the system, you do not want to mix it with 134a.

i believe that the factory setting is 0*, just make sure to disconnect the tan wire that wrightz28 mentioned before you try setting the timing.

[wrightz28]

It's on your emmissions information label, how to set your timing and curb idle and all that other fun stuff.

Usually is 0. For a little extra bang you can go to about 4 adv. on a stock setup.

got the ac done, no prob. love that nice cool air comming out now... havnt got to check the timing yet tho, maybe this weekend... ok back to the orig. problem, its still doing the same thing, the rpms will drop to about 500 then bounce to around 1000+ then drop and will keep doin it... was going to go ahead and replace the coil friday, whats best to get, a stock replacement or a stronger one like accel super coil?? and maybe get a highflow-cat but not sure on which i would need a single air tube or 2, and not sure if i should go with 2.5 inch or 3" my pipe behind car is now 3" with adapted on it to fit the stock cat thats still on there. was thinking of getting a magnaflow but the highflows i found dont have airtube.. and heard on news otherday we will be getting the sniffer test sometime soon, so trying to stay emissions legal.

one of my friends that used to own a similar car, little older firebird, said it sounded to him like the TPS was going bad, me not knowing much about these cars yet, but learning, would like to know where its at on the intake, and how easy is it to replace, and a good brand to replace, i looked online at the partstores and none seem to carry acdelco, have only seen wells(autozone), gp sorenson & neihoff at advanced auto, and i think bosch at oreilly... ranging in price from $20 gp & wells and neihoff being $27, thought neihoff was supposed to be a cheaper brand, from what i read from other places

[red92rs]

ok i replaced the tps, no change... where is the iac at, i have only seen a pic off of a parts page, but not sure where its at on the tb? i will go ahead and change that out too if its easy to do, looks like it should be but these things look simple and turn out to be a PITA like changing sparkplug...
