Check your timing, TPS could be going bad, insufficient air/fuel/spark...

i am having the same problem. tested TPS, fuel, spark, timing... nothing. at full throttle it is fine. wierd. it may be the o2 sensors. i am going to check mine and then try reversing the wires from each sensor. It is very frustrating because i can't go down the freeway without either gunning it or else slowing down.

Mine is kinda like that but mine isent slugish at all its like a small burst of energy on the highway. When i drive normal it does that but when i get on it its fine. I have no idea what so ever.

Well I am pre obd, running only one o2 sensor, which is brand new... Could this be my problem? Lacking a secondary o2, confusing the computer? or is it ok that I only have 1 because im pre obd?

let me know about what happens when you reverse wiring,

i hear you on not being able to keep it constant sometimes... sometimes i cant even tell if its doing it or not when crusing, slips in and out of stuttering.. this has to get fixed!!

so you have 1 o2 sensor sending the same signal to both inputs on the ECU? then yes this could cause a problem.

Unless my ecu only needs one o2 then yea, they must be sending the same signal, I guess i'll look into what to do about that, thanks...

any more help out there?
