Up on manifold but most are vacuum operated check again to make sure a solonoid operates this device .. usually when the egr valve goes bad the vehicle dies at intersections or stopping

I got a 1995 chevy blazer s10 with a 4.3 v6 engine wont start when it does start it is missing bad had it analized at auto zone came back a knock sensor, tps sensor, & egr valve what should i check...


In order I would go for the EGR valve, then the TPS. A malfunctioning EGR will keep the car from starting and make it run very rough if you do get it started. The car will run without the knock sensors so I would wait until it runs better before getting those. There are two knock sensors one for each bank of cylinders on the V6. Autozone should be able to tell you which sensor goes on which side.

  2. Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 30 ft. lbs. (41 Nm).
  3. Connect all wiring or hoses to the EGR valve.

Hope this helps (remember comment and rated this).

Chevy S10 Pick 1995 - Sputters and almost stalls when accelerating.


You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.

I have a chevy blazer 94 S10 still quit on the road.


How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

Egr valve


Here is a picture of the egr valve for your blazer. http://www2.partstrain.com/store/?Ntt=EGR%20Valve&N=9968%201588%204294967265
Quite pricey. As for changing it out I would head to your local library and seek out their online car repair sources. Be sure to take a jump drive or a floppy disk to take the documents back home with you. From your home print out the proper techniques as well as torque specs for the removal and replacement of the egr valve. Good luck.
