ok went to autozone and advanced auto parts to have codes pulled and the tool reads link error each time it was tested..one autozone worker stated that they changed the conectors or something that year and it won't read...
he said it'* for a 94 and up but maybe my car was manufactured in 93 and was just called a 94....afterwards I looked and it was manufactured in March 1994 so that had nothing to do with it right?
anyway they said they could test the Ignition module...under the coil packs and he said it failed and he tested it twice..but then he turned around and said that it is a possibility that this is not your problem even thought the machine said it failed i would get another opinion from the dealer/etc..and if i purchase one from them it cannot be refunded if the problem persists!
I had asked some questions about a scan tool on the neon site that I am a member of and one person said this:
does that mean anything?
thanks again

Rick '99 Flame Red R/T The GM product, older GM only required a paper clip to short 2 contacts in the OBD connector to get the CEL to flash, not sure if that was carried over until '94.
thanks again

He tested it twice and it failed twice! I am going to take it to the other autozone across town and see if it fails or pass there..If he mjust tested the module and it fail..is it a sure possibility that there is something wrong with it?
When he tried to pull the obd codes he got link error 3 times
advanced auto got it twice
the other autozone got link error twice also!

I had a similar problem with my 94 SSEi, cam and crank position sensors were bad, however, my car was throwing CEL'* at me every time I started it. Is yours?

Maybe that is a clue to figuring this all out

The light will not come back on for a while.actually..no light while driving..sometimes when i first start it it will come on then if i turn caroff and re-start then the light will be off ad not come back on again for a few more days..so it comes on intermittently..not at everystart-up but never while driving and never twice in a day no matter how mant times i restart

hey all I am taking it to the shop tomorrow..they quoted me over the phone that it will be about 30 bux to put it onthe machine..(i know it will be more expensive when I get it there) Anyways more people have responded with things that they think could be the culprit.
1. Anti-theft Security????
2.EGR valve
3. tcc selenoid ..tranny problems????
and one guy responded with this:
4.i worked on my bosses bonneville and it had all sorts of strange codes, stalling, backfiring and not running periodically. The computer also would engage the starter for no reason while it was running. We found that the air plenum on top of the engine was warped and allowing antifreeze into the engine. Ended having to do a head job and a new air plenum. I guess the mixture of antifreeze in the system was causing all kinds of faults with the computer. Not saying this is what you are having but GM let us know that the air plenum was a very common problem. May be worth taking off and looking in the intake. My bosses intake was flooded when I removed the air plenum.
now one last thing..i hear you just about have to pull the motor to get to the cam sensor/crank sensor..is that true?
thanks

A couple of comments here that I have learned.
The Series II N/A engine using a plastic upper intake manifold (plenum) and due to heat in the engine, it causes the manifold to warp and crack allowing coolant in....which is bad!!! It usually results in new heads and major engine work. The SC'd version however has a supercharger as its intake manifold....not plastic. Also the Series I 3800'* have aluminum intakes I believe. The cracking of the intake manifold is inevitable. It can be slowed with a 180T-stat.
As for the cam sensor (code 41) I have this problem too, the cam magnet is broken and in order to fix it, it requires major labour to pull the engine apart to get to the cam shaft. Usually, when a mechanic or a "pro" is in there, they will replace your timing chain. I have been quoted 4-5 hrs at $85 an hr/plus parts. Jrs3800 had the same cam magnet/cam sensor problem. But he had the resources to fix it outside of a shop. Some of us are not so lucky. I just live with the problem. It affects my performance tho...
I didn't think this was such a problem on newer (ie 95'* etc) only on the older 3800'*
