'01 Max sat outdoors for 9 months (east coast, humid conditions). Had both rear brake calipers replaced, installed new fuel pump, drove about 30 miles and TCS off and SLIP lights both came on. They go on and off intermittantly, maybe on for a half hour, off for a while, then back on. Check/service eng light also on but stays on regardless of tcs and slip indicators. Ideas?

 

First of all, there's about a million threads about this you should exercise the search function before posting.

Second, if you have an SES light on you should get the codes checked and provide that information with your post, it's almost always relevant to the problem you're having.

Regardless of that though, I'm going to assume because you said "tcs and slip" and NOT ABS that your ABS light is not lit up. So it's probably not one of the wheel sensors. I'd check your coils, one or more of them are likely starting to fail.

 

Had the same problem with my 2000 Coilpack
