So my 98 sport has been having a small issue lately. When I step on the gas from a stop/slow roll, it will downshift and rev, but right after the downshift, for a split second the power will 'surge' like I hit a wall, then run like normal.

There is a nice buck when I try to get on it. I'm thinking o2 sensor, but I was told it would throw a CEL if this were the problem. Maybe bad spark? Plugs? I have new wires on her, but maybe something else?

Hoping you guys can help!

 

Not ALL codes turn on the light. Could be o2 sensor or many other thing. What you describe is a hesitaion. I be looking for a fuel supply issue, filter or pump or injectors or TPS or CkPS.

 

Mine does the same thing sometimes, but mine is a stick. Any thoughts?

 

Check your TPS. My 5 spd on every shift it was like you turned off the motor for a second and then stomped on the gas. It would whip your head back and forth. And on the freeway at cruising speed it had like a miss. Fresh TPS all better now !

 

I feel confident that this could be the issue, going to order a new one now. Thanks!
