stall

You may have two seperate issues...Try pressing your enertia switch to determine if it is partially set. I have had the similar problem; diagnosed at dealer as bad fuel relay, then fuel pump, then after market alarm...all of which were replaced or removed. I found out while driving that by resetting the enrtia switch problem went away. It still happens sometimes...will eventually replace or bypass.

I think its on the firewall near the air filter canister at least on my 95 it is. I read somewhere that disconnecting the diagnostic display can help things IDK I will see if I cant find where I read it for the details.

I think he is talking about the emissions service engine light. I am talking about the OBDI I code display.

Truck is back at the shop. Claim it isn't the inertia switch or alternator. Maybe stepper but ussually when they fail they don't work at all but who knows.

mine did that about a year ago for a month. I made an effort to put decent gas in it for a while and it went away and never came back. Coincidence most likely.

Well a local shop said my distributor vacuum advance unit had a split diaphragm. They replaced it and set the base idle.

My question is now when I drive and I pull up to a light or come to a stop the RPM are about 1200 for a few seconds before it drops to just under 1000. Is this normal? I don't remember it this way. I am not sure if it seems weird because the borla is so loud or because I have been driving the 110 for a long time which idles differently. I trust the shop I just don't know.

thoughts?

Follow Up:

When I brought the truck back the first time for the weird almost stalling, they told me the stepper motor was missing the fiber washer. I knew it was as I had taken the stepper out at some point to clean it and the washer basically turned to dust. They put a new one on it and ever since I was having the stepped RPM drop that was driving me nuts. Today the shop admitted the washer was too big and causing the issue. As far as the stalling, an adjustment to my altenator cap seems to have fixed it.

I really hope this fix lasts.

Sounds like possibly a timing adjustment was done?

Not a 100% sure what was done. I picked the truck up and it is running correctly again thankfully.

Reviving my thread. I have driven my 90 75 miles since the repair. Was running totally fine until today. Pull up to a light, truck stalls and won't turn over. I sit there with every asshole behind me beeping. Finally restarts and promptly dies. This happens a few time until finally it runs but idled high for rest of trip. Went out again and it si running fine.

WTF

From the shop

Barry

Im sorry you are still having trouble with your D90 , we checked everything out on your vehicle / distributor / / coil / fuel injection / fuel pressure / wiring connections / idle stepper motor / fuel fittings / engine e.c.u. etc etc totaling four hours in labor , it was then left idling for five hours one day & four hours the next ,it was then driven by the tech & me for a total of 45 miles , SO ,it was completly checked out + left idleing for a total of 9 hours . it was test driven 45 miles by my tech & myself & 75 miles by you ,before you had another problem ,I think I have done more than anyone would have to resolve this problem , that is obviously intermitent , I am probably upside down with this problem four or five hundred dollars ,so I am frustrated as well ,there is NO way I would have given your vehicle back if I thought it still had a problem , if you would like , I will drive it for a few days & see if it does it to me & try to get to the bottom of it .

I really don't know. This isn't something I know anything about.
