Car stalling after getting stucked in traffic

**chewbaka** · December 1st, 2014 01:12 PM

My car (City 97, AT) suddenly stops after driving from Teacher's Village to Megamall (1 hour drive). The battery seems to be dying down ( even in neutral) when the aircon starts (rpm going down to zero) after falling in line to park, I had to rev it up but in the end engine shuts off and I cant start it anymore (no click no nothing). This was 9am, I left for work then I went back at 3pm, car started normally and I was able to get back home. What could be the problem.

Note: The car seems to be having trouble once it gets stuck in traffic/ getting hot
- I have replaced the fuel filter
- I have replaced the ignition coil
- I have replaced spark plugs and spark plug wires
- I have tested the battery and it reads 14.
- battery clamps are tight.

I'm at a loss. Any help will be appreciated.

Thanks for the quick reply sir. 1 year 3 months. One more thing, I had a 1 SM motolite battery as suggested by my battery dealer.

oh ok.... have you had your fuel pump checked? also, are you experiencing erratic RPM? o bigla na lang namatay?

That's something I'm looking at the fuel pump. Napakamahal daw nito. RPM is normal. Pag mainit na yun makina medyo bumababa to 600 RPM with aircon instead of umakyat ng 900 RPM. Normal RPM at 800

looks like the typical pgm-fi main relay problem (just my 2 cents)

Thanks for the input. I've been doing my own google search and I read a lot about the PGM. what does this stand for? Is this an electrical or mechanical problem?

also a possibility.
it means Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic fuel injection system for internal combustion engines which injects the right amount of fuel per cylinder based on specific engine data, available since the late 1980s.
its a computer/electrical problem.
