Troubleshooting Request! [SOLVED] Options

[rave2n]

Hello all. On my way home from work this evening, the cellie died.

I was just taking off after a light, and it started to feel like it was stalling in 1st when the gas about half down. It seems to have recovered and was going alright. Drove normal...til the next light. Did it agian, but worse.

After stalling completely while going 35, pulled over. Had trouble starting up, but would start. Idle was crazy, but tapping the gas you could get it up to 4k rpm easy. That didn't last long either. It started to drop asoon as I hit the gas after that. Now it'll have a really rough start up, then run like crap for about 10 seconds, then just dies.

I checked for any obvious leaks or anything of the sort..nothing. My limited knowledge of engines is a hinderence atm. I do know, you need air, fuel, spark. I have air, I have spark. So, my question is...do you guys think my fuel filter, pump, or injector is bad?

The spark plugs are less then a year old, the only recent thing i've done is got a oil change, and put in LED BA-15 bulbs in my rear lights =P

Any assistance would be greatly appreicated, as right now its sitting in a parking lot of a not so wonderful area. Hoping its something I can fix quickly and available at a local shop..

My car has been doing this for the last week or so as well. I was pretty scared and stopped driving it because I have almost an hour commute in stop and go traffic and that is when the car stalls the most, on low rpm. I too have had similar experiences as well with sputtering at low rpm, engine going up and down just like yours on your clip. Please keep my updated if there is any changes good or bad. I called a trusted mech and he said that it could be many things but if it's the Fuel pump then I should not continue to drive it until it get's replaced. But you said you already checked your pump right? I hope things get better for you. In the mean time I drive it every few days to close places but am too scared to drive it far. I get a few sputters every 5 minutes or so still.

Yea I wish I had a answer, I'm still looking myself. Its been worse the last few days, its comes and goes which makes me think its electrical.

I removed my TPS yesterday and checked continuity at .020 mm, and up. It seemed to be within specifications, but the haynes manual is very limited on information for the 7a-fe engine. The only one that was close to my TPS was the 3sge, all the others were only 3 pin connectors where as the 3s-ge was 4. So I just went off that.

I've been spraying carb cleaner in the altenator just for giggles, surprisingly it worked better for a few days after, payday is right around the corner, so I might just invest in another alt even though I was trying not to spend money on this engine being I was saving for the swap, but it appears you have to spend a little to get a little.

I hate to just throw money at the problem and hope I find the issue. I'm debating on just taking it to get a dianostics and hope they can just tell me what it is. I've probally already found the issue, just didn't realize it. Being mechanically inclined is great and all, but does make up for lack of experiance as i'm learning =P
