Hanging RPM, p1174 code

Cronusheart · 12-30-2015, 02:50 PM

Hello,

About a month ago my car threw a p1174 code. Since then I've noticed that the rpm hangs at 1400 when coasting in neutral, and will drop to idle when the vehicle stops. The problem appears to be intermittent, and I can't figure out under what conditions it occurs. Any ideas on how to correct this issue?

Thanks, SaturnFans!

Ignore the problem any longer and tipu will blow up your engine

Could you explain what is causing the issue exactly? The cel went off and has not come back on.

Thanks

The link explains it just fine (that's why I put it in my post), but basically, fuel trim balance is off, some cylinders are getting more fuel than others. There is no void reason for this besides bad/plugged injectors. Injectors in l61/le5/lsj engines are known to plug/go bad. This is why there is a tsb stating to use top tier gas in these engines. Replace the old design injectors with the new ones and get the ecu flashed.

Thanks man. If I use top gas and fuel injector cleaner, can I put off swapping out the injectors for a bit?

I wouldn't. The damage is done, and likely permanent.
