Dudly it is a 97 van. The key dance is different than the M. When you do the key dance, the service enginge soon flashes. Instead of giving an actual code, it flashes a code ex service engine soon light flashes 1, pauses flashes 2, pauses 5 155. I am guessing 125155 is the code. Can u give me a call? 630-398-1392. It's louie.

get the fuel pressure checked, if its low , it will do just what your describing, its LEAN


also things to check, map sensor, fuel filter,
fuel presssure wont toss a code, maybe a lean code once in a while, as the map sensor, unless its way off, no code,, sucks dont it?

Because of the rain the last day, was not able to do much. I did install new spark plugs(whata fn *****) started the car idles perfect. With the car in park hit the gas, and hesitates and back fires through the intake. Tried disconnecting the electrical connection on the o2 sensor did not help. I think possibly having a timing issue. Does anyone know how to check the timing? Also, thinking of replacing the cam sensor? Does that make any sense? Please help really need to get the van going! Losing my patients dont have any hair to pull out! TIA Really dont need any unnecessary out of pocket expenses.

usually when an engine barks out of the induction its timing...timing belt jumped a tooth or two. Do not know anything about 3.3's or even how to tell you to check the timing. But I know who can help you.
Daytrepper is the man!! Hopefully he'll see this and respond.

I think if a cam sensor went tits-up, it would not start at all.

How may miles are on the timing belt. Six years or 70,000 is about all you get out of them. If you get anymore...youre on borrowed time.

Its 3.3,, no Timing belt,, its a chain,, and it would have to have a hell of a lot more miles on it to even think of jumping,
im telling you,, check your fuel pressure
