If it's running, put that cable to use.

unfortunately I still cant figure it all out. I asked for help on the Scan and Tune section but no help. I've got Windows XP and cant figure out if thats whats causing my Tunerpro RT not to work. I would love to use it though.

Your dizzy is in wrong,just pull it and do it right(look at Agent 86's pic),in another statement you said timing was about right???Why not right on?is it because you can't turn dizzy ? did you disconnect est before setting?First put the dizzy in right then go from there.Also take a long screwdriver and a light, turn oil pump drive shaft so the slot is in the 5 o'clock posistion this may help you drop the dizzy in

The relay you refered to is the fuel pump relay. I'm not going to count the posts for you....but several of us are trying to tell you YOUR DISTRIBUTOR is not even close to the proper orientaion. I hope you at least have a Haynes manual. You're never going to get this car to run right until your timing issue is corrected. The idel could very well be attributed to either the IAC or a vacumn leak, but you'll never know until you follow the proper steps!

yes, i pulled it when redoing the intake gaskets. but that where it was when i pulled it. all l98's i have seen or clocked like this. you can set it up with it pointing at 3 o'clock but your oil temp sensor and pressor sending units are right there as well.

yes , start there I would add you will turning the crank by hand. put thumb on spark plug hole to assure compression stroke or with timing mark then on TDC. (or with v. cover off.)

2nd, then you set rotor position (this is a good time to pull dizzy to reorientate having distr. body where you want it).Rotor should be orientated slightly before no.1 THEN go through firing order (RE-DO!). Make sure all wires are completely snapped on to the terminals.

Like others already said, that F.O. doesn't look right despite your saying it is, look at my pics. at where no.1 is. The location of the distributer shows me someone had it out and set it back w/out consideration to location to the firewall (one tooth back). It would still run, the difference is the lack of room to turn the dist. for timing correction.
From the car being able to start shows you have spark, fuel and air. If no-one has changed anything else, another thing that could contribute to timing issues woulld be if the dampner ring has slipped and is creating a ficticious timing mark.

3rd, Quit worrying about what a mechanic told you if that was entirely correct your car would running correctly wouldn't it? start working the problem step by step.

If you have a 2nd person available while your finger is over the hole have someone click the ignition over (dont sit there and crank it)..Youll know when its on compression stroke, a rush of air will try and blow your finger off the hole. Take your time and try it again.

Enlighten me...

Based on what I'm reading, it sounds like my distributor is in the wrong location too.

However, I'm able to successfully time to 6*BTDC.

The car seems to be running great.

I do have a puff of black smoke coming out however.

Other than having it in a slightly inconvenient location, is there any other issues I could have for my distributor being located slightly different?

With it running well and able to easily get the base timing, it sounds to me like everything still lines up fine.

Is there anything I may be missing since it seems like everything is in line?

I'm trying to figure out why I'm running rich right now, so every little bit of info is helpful.

In case you don't know, that should be your MAF burn off relay clicking.

The only thing with the dizzy being where you have it would be accessing the cap screws. Other than that, it will still do the job.

OK, you took it to the wrong guy to begin with. Find another tech/shop and take it there.
As for not being beyond your mechanical skills, its not about mechanical skills. Its about diagnostic skills. And apparently, it is a little beyond yours. No offense.
Something to consider; How much money do you earn an hour? If you spend 10 hours on this thing, and not figure it out, would it not have been cheaper to take it to someone who could find it in an hour? Not to mention the parts you may end up buying/replacing needlessly. Not to mention possibly saving your sanity.
I know conquering something like this gives you the warm fuzzies, but it may also cost you more in the long run.
Find a really good diag guy, and take it to him. Make sure you dont have to pay if its not fixed. Thats my policy, and should be everyones.

Awesome... exactly what I thought. Logically I couldn't figure out how it wouldn't work. So I'm happy to hear my logic makes sense this time!

I use one of those crazy flexible carburetor nut drivers to pop the cap screws off with ease. That said, I'm not gonna mess with mine!
