My engine light is on 02 windstar. had it scan said it was running lean. It really acts up when it rains

Question

i just had a tune up done when the light was on before and changed the egr valve and everything else with it. I am so sick of this car

Answer 1

that was a good answer and have you change th efule filter or added a bottle of fuel treatment

Answer 2

The most common cause of a lean code is a vacuum leak.

Start the van and try listening for a hissing sound. Also check around the PCV hose real good, cause the hose gets oil soaked and starts to leak.

If you still can't find it then buy a can of carb cleaner and spray it on the hoses and intake. If the idle changes then you found your leak.

Hope it helps, good luck.
