So 2 days ago I disconnected the battery to remove an Amplifier from my car. When I cranked it back up. I noticed that the idle was below 1000 rpms and the oil light flickers.

I also noticed that when the engine is warmed up the radiator fan remains on and the coolant needle on the cluster gauge rises a little. Not too much but it is noticeable.

Anyone know what to do with this symptoms?

 

-Does the idle go below 1000rpms when you reconnect the amplifier? Is it throwing code when it flickers?

-Try simulating the problems with and without the amplifier connected & unconnected while pulling codes.

-And where is the coolant needle on the cluster gauge? in the middle? at the top? where?

 

It's just a little above the middle. I'd say like in the middle of the middle m 3/4. Understandable?? Lol
