I have Honda Civic 98 EX. ever since i got the timing belt, and water pump changed, my "check engine" light turned on. and the computer says's it's Idle Air Control Value,
So i put in the new IAC and after about 40 miles the light came back on.
I showed the car to a mechanic. and he said same thing. so he put the used IAC in. and it worked fine for about 150 miles. and reset the computer and the light turned back on after 80 miles.. i don't understand what's causing it?
anyone know how to fix the problem, I'll appreciate it. b/c my inspection is expired, and I'm trying to get it fixed quick.
Troubleshooting P0505
Probable Causes
1. Vacuum leak on engine (checked that)
2. Dirty throttle body (not sure, how to?)
3. IAC motor defective (changed twice,didn't work)
4. Poor electrical connection to the IAC value (mechanic checked it, it's not that)
so what else could be worng?
