Hey there,
I have a 94 Rodeo V6,3.2 with 150K miles on. Today when I was driving on the highway going around 70 (rpm is between 2k and 3k I think), I noticed I start to loosing power and engine started to bucking. Then I found the check engine light is on. Occationally the light would be off and the car seemed to be normal again, but then it would come back and I could felt the enging bucking and losing power. It is especially obvious when I am driving uphill or accelerate. I have to drive below
60 and not sure what happened. I did add gas this morning. I changed oil a couple weeks back and replaced new air filter. Any thoughts? Please help. Thansk!Cmbaus
