Hey all! I have a 96 chev s-10 blazer 4x4. I reacently replaced the TPS sensor, EGR gasket, and Crankshaft sensor (with a "learn proceedure" done). Damn thing still goes down the road "buckin'" at times. Every time it "bucks" my Brake lite and Anti lock brake lite goes on.....then goes off. Strange. Any ideas? Thanks a lot.

 

could be a tranny trouble.... feel like you just went across a rumble strip?

 

Does the tach go crazy when going up hills? When my tranny died on me. The tach went nuts when I was driving up a hill. I had all forward gears NO Reverse.
