working on a 98 optimax 135 Mariner and it seems to work great other than once in a while it will completely stall on me. I took it to the dealer and they hooked it up to the computer and it comes up as the TPS sensor. I have had it to 3 seperate dealers and they all say the same thing but it still does it after they make an adjustment on it, I was wondering if anyone has similar problems, It will work great for a day or a week then all of a sudden it happens again, any help is appreciated.
