Idle Problems.

Asked by Derion Jan 10, 2019 at 02:00 PM about the 2005 Honda Accord

Question type: Maintenance & Repair

I got a 2005 Honda Accord V6 and it
starts but won’t idle. I’ve replaced the
battery, EGR valve, air filter, Air intake
hose, MAP sensor, and cleaned the
throttle body. It also sometimes only
starts when I hold the pedal the
ground. Sometimes I get lucky if I
leave it alone for a day and then it
starts and idles but then stalls out
after around 5 minutes or if I switch it
into a gear. There are no codes
showing up on the OBD2 Scanner
either.

Check the connectors at the crank, cam and TPS (Throttle position Sensor)I'd bet it either a short somewhere in the TPS HARNESS or the TPS ITSELF

Check/replace fuel filter. That's a potential problem that does not usually show a code. Filters should be replaced every 30K miles or so. The idle air control valve might be bad, but that should show a code. Might just be clogged.
