Hey all, I have a 98SE AT 4x4.
When I'm driving a bit hard, meaning that when climbing a slight hill not too fast (2nd) or when I'm on 2nd gear and the rpm starts to go higher (right to where it would shift to 3 if I was on D), I can feel a slight surge. I don't know how to explain it, it's like I can feel a slight variation in power...

Truck has 135K, New Sparks. Dealer said it was a dirty airflow, so they cleaned it with a spray can... Still same problem.
Thought I'd post here before taking it back.

PS: I remember I put in half a bottle of Redex Injector Cleaner shortly before that started to happen. Don't know if it is the culprit cos the truck drives normaly when I step on the gas fast...

Thanks all.

Could be you moved some deposits in the fuel system, more inj cleaner might fix it.

Thanks for your reply. On a side note, which cleaner would you recommend? I think here we have STP products... Which brands have you found to be most suitable for 98 Pathy?
Any more thoughts guys besides what IanH suggested?
Thanks a lot.

I have used the chevron product techtron (? SP)
There are Two, One is better more concentrated, I used that one, i will look see if i can get more detail
I think its Ok, but people on the forum in the B14 section say not to use injector cleaners as they are not good for injectors, but i dont know if this is true.
Good luck....

Thanks for your reply, I have changed the fuel filter less than 5k ago at the dealers.
