Why the check engine light comes on and off runs great

The check engine light is on to tell you the computer has found a problem that will affect performance, gas mileage, or emissions.
Such as the code 171 you asked about.
Code 171 is for the fuel mixture on bank one being too lean. The O2 sensor is telling the computer the fuel mixture is too lean and the computer can not make it rich enough.

Engine light on, the car was running a bit sluggish. i replaced the plugs and wires and it runs good now. but had also found out that the 3rd cylinder had misfired. cleared the code and it still hasnt...

See if you can pull a code off the check engine light would help. Check fuel pressure at engine in case you have weak pressure will cause hard start/prolonged cranking. Other emissions related components can do this also, but if you get a code can narrow it down.....Mike

Code 171 and engine light is on

--BANK 1 = DTCs P0171 (lean) and P0172 (rich)

-Check intake air system for leaks, obstructions and damage.
-Check air cleaner element, air cleaner housing for blockage.
-Verify integrity of the PCV system.
-Check for vacuum leaks.

I would try cleaning the Mass Airflow Sensor first. A dirty Mass Airflow Sensor is a common problem for triggering PO 171 & 174 codes.

Good luck and keep me posted.

89 Honda Prelude failing emissions rich

is everything stock? and you have catalitic converter in place?

Stop by Schucks auto supply and have them run the codes. i'm sure there is a code if you cant pass emissions. your check engine light bulb is probably out.

and usually the first cause is the first o2 sensor.

Sluggish performance and engine light - added new plugs and oil

You need to check for engine codes to see what is wrong. Bring it to a parts store for a free scan for codes. The check engine light indicates a problem, probably the emissions system, which is causing the poor performance. The parts store will plug a hand held scan tool into the cars diagnostic port (usually located under the dash) and 'read' any codes stored in the cars computer. They can them tell you what code #'s come up, what they mean, and how to correct the problem. If you have any questions after that, post them here w/ the code #;s for further help.

PO 171 and PO174 codes but different problem

transmision shifts are based on engine load imputs a 171 and 174 refer to a lean condition therefor the shift is being based on an assumed cold engine so yes it may be related

Engine light

the check engine light notifies you of any faults within your emissions systems. Many parts and systems within your vehicle are emissions related but a sensor must notice the fault the first and then send a message to your ECM(electronic control module) otherwise known as your computer. this will trip the check engine light. If you have noticed no attributes related to your emissions system such as rough or uneven idle, sluggish accelleration or missing throughout the driving or idling range (slight loss of power) then there is the probability that you did not put the gas cap on tight enough. Always make sure you turn your cap until you it clicks a number of times. After doing this and keeping it in mind you can try to reset the computer by removing the negative battery cable for a while (3 minutes mimimum) and reattaching. If the light is now gone and does not reappear you have found the problem. If the light is still on immediately after reattaching the battery then your computers memory has not been cleared. If the light comes back on then you can try to pull the codes from your computer if it is OBD1. You can tell this by looking at the diagnostic connector under the dash right around where the drivers left knee would be. If this connector has 2 slots with metal connectors and the far right either at top or bottom you should be able to get the stored fault codes. If there is only one or no metal tabs in two adjacent slots of the connector then your system is OBD2 which means you would need to have the codes read with a scan tool. Most mechanics should do this for around $40. If it is more call someone else.
