Code p 0028 refers to intake valve control solenoid circuit , bank 2 ---range performance problem===causes--wiring ---intake valve control solenoid
this solenoid controls the advance / retard of the valve timing for the inlet valve camshaft and will account for the idle problem and the engine light
take it to an accredited service center who has experience on your make of vehicle and have the wiring checked or the solenoid replaced

Engine light stays on while running, low idle

You need to have the pcm scanned for fault codes. If it is newer than a 1996 model, Autozone will scan it for free and tell you the fault codes. A mechanic would go from there, based on what the codes reveal. The low idle is probably a symptom of the fault.
Anytime the MIL light stays on with the engine running, the pcm (engine computer) has detected a fault and will turn the light on. It also stores a trouble code in memory, maybe called a pending code if only recently started, but the code can be found with a hand held scanner, hooked up to the port under the dash for code retrieval.
When you have done the repairs, and the old codes erased, you will see that the engine light always turns on when the key is turned on. If there are no more problems , the light will go out very quickly after the engine is running. It is a bulb and computer check that the light is on with key on, and stays on until the engine is started.

Cant seem to get the idle are timing locket in seem to idle to high the check engine light stays on

Find out what code the CEL is throwing. It could just be that your idle needs to be reset. Or you got the timing wrong when putting your car back together and it's running excessively hot.

I have a 2001 Acura 3.5Rl and I want to know why my check engine light stats on after it's been reset? And is the idle sensor engine related? How much does it cost approx to repair idle sensor? Is it...

The check engine light comes on when there is a failure. If the failure is not fixed before clearing the codes than the computer turns the light back on because there is still a failure! In order for the light to stay off what ever is not working needs to be repaired. Then the codes can be cleared and the light will stay off. What code specifically do you have. It should be a P followed by four digits (P0128).

Truck should not be driven when the check engine light flashes, means you have something very wrong. Take it to a place like Autozone, they will check the code (check engine light) for free. There will be a code on the print out they give you, starts with Pxxxx. Let me know what the code is. What was done when you did the tune up?

Service engine soon light is on. Garage said they got a p0101 code. Engine idles OK but when throttle is applied engine starts to bog down and then the light starts to blink. If the throttle is reduced...

The code means there is a problem with the air mass sensor or circuit.
There are lots of possibilities, but the most common is that oil/water vapor foam from the PCV coats the air mass sensor and makes it inoperative. I suggest removing the sensor, cleaning it, and trying it again.
You can check it more accurately with an ohmmeter, but I don't know the normal reading range, and it should vary with air volume anyway.
But you can make sure it is not 0 or infinite ohms anyway.
Symptom is what you would expect, that the engine does not know you have applied throttle, and is still only giving idle amount of gas.
Perhaps a place like Autozone will check the air mass sensor if you bring it in.
If that is not it, then it is probably the control unit, with can also be brought in and tested.

Hi my name is Allen!

When the check engine light is on this means there is a problem somewhere in the powertrain control system, which could be almost anything.

Here is what I need you to do, drive your vehicle to AutoZone or another auto parts store near you and have them pull the codes for you. Then get back to me and let me know what those codes are, and what the scanner say the code means.

We will move further with repair procedure after I know what the code or codes are.

Waiting for your reply!
