Hi. I have a 1996 Explorer. Recently the check engine light came on, and
it began stalling (or trying to stall) the first time you press the gas
after starting it up. Once you can get a couple of pumps of the gas pedal
down, it is ok again, it's just the first time, or couple of times, you
press the gas that it stalls. Anyone know what may cause this?
I went to Canadian Tire. Don't know if we have Autozone in Canada. $66 to
read the computer. They say based on the codes it looks like a defective
mass airflow sensor (whatever that is). Apparently an expensive item, so
I'll try to find one at a salvage yard.
No, no, no. You can clean it. Do a search here, it's been covered.
I'm on my way out but I'll check first thing in the a.m.. If no one has
shown you how I will take you through the process step by step. It just
needs cleaning but it's a little delicate, that's all.

You can see similar instructions and pictures here:
You will need a set of tamper resistant torx bits available
at most decently stocked parts houses. You will need either
denatured alcohol or residue-free electrical cleaner which
is my preference. You can get it at places like Home depot
or a good hardware store.
It is a T-20 Torx bit but, it has the center hollowed out to
accommodate the little button in the screw head put there to
keep out regular bits. I say a set because you can usually
get a set of them to use with a 1/4" socket or nut driver
for about $6US. I have no idea where you would look for a
single bit in that size with the tamper resiatant feature.
I know you got a reading but your original description sounds more like
the Idle Air Bypass Valve (another easy cleaning job). Dirty MAF
usually causes a strange grindy sound upon acceleration (it's pinging).
I think I have the grindy sound you're talking about. I just chalked it up
as the sound a truck makes working harder than a car (I have only had the
Explorer for a week). The error codes from the shop are P0102 - MAF
circuit low input and P1100 - MAF sensor intermittent. I'll go out now and
get those bits and cleaner and see if that fixes the problem.
Thank you all for your help and advice, I truly do appreciate it.
Just thought I'd come back and post the solution for anyone who may read
this thread while looking for help. The problem in the case of my vehicle
was a damaged wire, somewhere between the MAF and the computer. Once the
wire was located and replaced, everything works fine.
Thank you everyone for your suggestions.
