Went to the grocery store tonight and my 87 GL10 (2wd wagon AUTO Trans) was running like crap. When I left the grocery store the car started up normally and I made it about 1/4 mile and it started sputtering and died. I tried to start it again and it started but imediately died again. I hit the key again, it started, tried to feather the gas to keep it running but it basicly had no effect to keep it running. Towed it home. It still starts for a few seconds then dies imediately... check engine light is NOT on.
Its been running crappy for about a week and thought it had something to do with the modulator on the trans (one on order). Every morning it had a hard time shifting into reverse and shifting into first and second gear. Also coming to a stop it would not shift down to first. Id hit the gas, it would rev then drop into first and squeel the tires. I'd been working the throttle to get it to do what I wanted but Once it got into third gear it ran pretty good.
Also a few days ago I put valve cover gaskets on it. During this process I removed the two small screws from the MAF sensor and removed it from the aluminum tube near the air cleaner. When I started the car after I was done with the gaskets, it would start but not stay running (same as my grocery trip) but if I would step on the gas it would stay running. After working the throttle like this 2 or 3 times it idled fine, but tripped the check engine light on (code 23-Air flow meter or circuit). I reset the CEL by plugging the green and white connectors together just before my trip to the grocery store tonight.
Anyone have any ideas what this could be?
Again the Check engine light is NOT on and the car will start for a few seconds every time, but no throttle response.
