Hello all,

First of let me introduce myself. I own a 1991 S-10 Blazer with 180k miles on it that was passed down to me after my grandfather had passed away. Now I am hoping these forums will help me out with some of my issues.

My problem: My car randomly dies out in different scenarios
1. It dies at the light and fires back up
2. It dies while going about 20 mph (Guessing because no speedometer)
3. It dies right after cranking.
4. After dieing it dies again and makes a huge rambling noise.

Now here's what I have done since I have had the car:
1. Changed the oil out
2. Had a well established mechanic change lines/ re-run fluids (5 months ago)
3. Replaced the anti-freeze (Alternator cut into my line)
4. Replaced battery and alternator (Connections are sturdy)
5. Ran sea-foam and injector cleaner
6. Ran new vacuum lines.
7. Replaced fuel pump

Also something worth noting is that around where the oil is put in it is wet as if something were to be leaking, but no clue where from?

Is it unusual for my accelerator pedal to be so hard to press down on at times? I had a friend (Volvo mechanic) look into that and thought that the throttle might be junked up but it's not. Sometimes the car will want to put some power to the engine right after I take off my foot but it stops as soon as I tap the brake.

Any idea what I can do to see what is causing my problem?

When I used my code reader all it gave me was speedo. That's all. Nothing else.

 

check for play in the throttle shaft, there should be none. The shaft has bushings that can wear out, casue vacuum leaks, and your "hard throttle pedal" makes me think of it.

 

I might know your problem. I will tell you what I think it is just need more info, and i might know how to fix your speedometer as well

 

check to see if you have a broken motor mount . your engine will lift under torque and you will bend linkages.
