Doing CPS/random stall research...

Hello again forum, it's been awhile since my last post, but as the life of my GTP progresses I find myself time and time again coming here, lurking the site...:th_biggrin2:

I have experienced 3 random stalls in the past year and 2 of them with-in a weeks time...

I have read many things about the crank position sensor being the culprit 90% of the time, and others being MAF, bad battery/alt, fuel....

Also, when I experience the stall, it has been while not moving, idling at either a light or in traffic...

I have read somewhere if a battery is old, it can cause stall issues....Is this correct??

I have a 4 year old battery that looks failry beat...(wet)

The reason for my posting is that as life progesses, I have less and less time to research/repair/experiment on my vehicle...

Just looking for some quick pointers to I can head in a semi straight direction before chewing up my time going on a not so straight direction...:th_scratchhead::th_biggrin2:

I can and will (if needed) bust out the cps, but I would really like to test a few things before going loco...

Should I just unplug the MAF and drive to rule out the MAF?

How old is considered "old" on a car battery?

If heading down the cps route, I have the fsm, so I would just need time and tools...I would need a puller for the crank pulley, correct?

I read also I need some bolts from Ace so to use the puller correctly? Anyone shed some light on this for me?

Any advice would be greatly appreciated...

Upon further review of the battery, I've found the negative side stud is corroded badly...Prob be my 1st, cheapie fix to see what happens...

cleaning the TB is also a good place to start.

the battery should have a date on it showing how many months its life is. 4 years it could be at the end of its life span. a parts store can test it for you.

This problem is a TSB. The negative stud on the frame rail also corrodes heavily.
