hello,
I have a problem with my acura 3,2tl 1999.
When I'm starting cold engine, I have to turning 4-5sec before it starts. There is no problem to start with warm engine.
When starts ( cold or warm ), RPM ranges is between 400-700 and sometimes engine turns off.

PS. I need to add, a few days ago I had an incident: a coolant leak, so the temperature was in red marker for about 5-10 minutes of drive. After I saw it, I stoped the car, waited about 15 minuts, repeaired leak and refilled a coolant fluid. After that everything was ok for 1-2 weeks. Engine Power is ok, temperature is ok.

What could be the reason? I don't know, check compression ? check valves? what else? Please, help me what to do ?

Best regards, Luk.

 

ps. I forgot to add, that sometimes ( 1/5) everything is OK. Acura starts normaly, RPM is OK...
OBD2 shows no any problems.ps. I forgoted to add, that sometimes everything is OK. Acura starts normaly, RPM is OK...

 

I checked jusy DTC, I have a P1457 DTC code.

 

Welcome Luki2604 !!!
Check out the 2nd gen DIY's. The EGR passageways may need cleaned. Try some fuel system cleaner. Ya may want to consider having the cooling system pressure checked for leaks. The 1457 code indicates an EVAP problem. Reset and see if it comes back.

 

hey,
stil P1457.
It is normal clicking all the time?
I tested this clicking valve like in Manual, seems to be ok.

 

P1457 indicates that a leak has been detected in the EVAP control system.
The clicking that you hear is from a sticky "Purge Control Solenoid Valve". A common issue normally resolved by replacing the valve unit.

 

OK, but when I plugged the power supply 12V directly to the valve, then it works normally- without clicking- just one click to OPEN the valve or one to CLOSE the valve.
So it makes sense to repleace it?
PS. wires ro PCM are OK.
