It shakes when stopped at a light or on idle sometimes
i changed the plugs, wires, cap rotor, and fuel filter hoping to solve the problem but it still persists any advise?
Shakes how? While stopping? Or solely while idle, Engine light on?
If if shakes while stopping you need to check you're wheel hubs and or Suspension ,
Shakes at a light, You may have a bad fuel Injector, Check you're psi in you're fuel pump, A TPS would cause low idle or sometimes high idle, With low idle and a bad motor mount it would shake,
I know theres a few things I'm missing but,.. I have a major Headache atm so I'll get back to you with some more, when i can think better. :)
Try replacing your idle air control valve. or yours might just be misadjusted. drive for about 5 min. at 40 mph. this tells the ECU to adjust the idle air control valve. it helped with my blazer
Check the timing I just bought a 1994 s10 blazer 4.3 vortec engine it was shaking when stoped and would even cut itself off.
