1997 Honda Crv. Vehicle stalls without warning and will not start for about 10 minutes. Then drives ok for 20-30 miles and then stalls without warning.

Check crankshaft sensor.

which engine??????????????????
one of those is false. i bet. ever the the 60k mile tune up this decade ? Yes, good, no?, well, what did you expect?
driving honda's top death is just that....see end. below.

my guess is you are doing one test wrong. , (i cant see you, so...)
THE ROPES: (called basics ) order counts big time.

1-good engine? (compression at 150psi or more x4? or x6 if V6.
2-good spark at all cyl. and timing right. check timing.
if timing of spark is way off the cam belt slipped, no service ever done is cause.
3-good fueling, it runs. (if not flooded (is it) test fuel does work here.
in this step.

turns off driving, but how did you do that, if it wont start?????
my guess is the stalls were the preamble to the end death


exceptions, to above. ( 1st CAT ,is rare)
1: CAT melted. (there is a cheap simple test ,ask)
2: ISC stuck closed, (Aka; iAC electric) use 10% throttle to mimic this bad part and car starts easy , this trick is in the operators manual.
3: EGR stuck wide open, see 10% above, trick. or clean it.
4: engine flooded, see opr. guide for WOT cranking
you crank at WOT. wide open throttle, and EFI cuts all fuel, clearing
the flood.
so, do you look at spark tips for BAD COLOR or soaking wet with fuel.
Look at them. (they speak volumes)

old spark plates and winter hate each other..
do the full tune up, filters ,cap rotor, wires and plugs. and magic happes, and if the timing belt is old, BOOM
the HONDA IS NOT FREE RUNNING at all.
that means ,skip belt service, a $25 belt can wreck the whole engine.
or at the least just bent valves,
on this engine, my cylinder leak down tool comes out 1st.
(your symptoms)

PLUGS LOOK LIKE THIS?

hi can you have it scan for a dtc code to know what the problem is or you can buy a diy scanner to do it your self

Considering that it occurs more often with the a/c on, it is most likely a problem with either your battery, where it is too weak to sustain the engine output, or with your alternator. I advise checking your battery, and if that isn't the problem, checking your alternator. If neither of those seem to be the problem, its also possible that it is your torque converter, or a skewed setting in your ecu, both of which would most likely need to be checked by a professional.

could be a sticky valve issue...
I had one of these trucks and it had this problem.... I sold it...

You need to replace your coil pack. It sounds to be over heating which results in no spark being sent and the enige dies. Very common fault and easily fixed.

Thats why you dont take your vehicle to some kid at the stereo shop without a wirnig diagram to poke around and screw up your car. You should have OK'd the Honda dealer to fix it, and have the manager from the steroe shop pay for any repairs. Sounds like a bunch of parts changers are just replacing parts without testing. Once you buy parts like that, there's no refunds.

this is your ignition switch failing. Typical symtoms when stalling, speedometer and tach dropping to zero, some warning lights not lit, power failure. The internal contacts are shorting due to poor design and engineering. This causes vital engine/vehicle electrical failure, causing the stalling(happens more often in hotter/humid weather). There is a recall in place for this in 2002, over 1.5Million vehicles from 97-02 Honda/Acura models affected. Owners were notified in 2002!! If your vehicle is part of this recall, honda may repair for free. Call your local honda dealer with your VIN# at hand, they will give info on this recall and may repair for free. Otherwise the switch cost about $45-$95. hopefully this helps...please rate...thanks

If the fuel filter has not yet been changed have it done,

hi check your power steering pressure sensor and eld [electronic load sensor ] as the prower steering will put extra load on the engine and is compensated by these devices yates210456
