P0236 p0455 My check engine light comes on if i quickly go from 2k rpm to 3k rpm and it reads codes p0236 and p0455. also, if i go up to 5-7k rpm my check engine light flashes, but turns off fairly quickly. I feel no performance change during either phenomena, but I would like to get it fixed. Also, there is an oil leak somewhere on the left side of the engine around the belt system.

    These errors are related to the MAP sensor and the emissions charcoal cannister. If you go to AUTOZONE dot com and make a free account you can access the free repair guides to see how to replace the items. The 455 code means that there is a large leak in the system and it could be the hose to the cannister is damaged. The MAP sensor is about 100 USSD and is easy to replace.

SOURCE: OBD 2 codes p0442 and p0455, also smell of fuel from ventalation system

These codes indicate a leak(s) in the fuel system, it can be anywhere, you will have to crawl under and try and see where the leak is, you will need a scanner to turn off the light after repairing the leak(s)

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

Check coil #3 on v6 and #4 on v8. Usually the coil closet to passenger read side of engine. You probably dont feel a misfire, but put the car in drive and firmly hold brakes down. Rev to about 2k or 3k rmps. If it stutters thats your issue.

What would cause a p0236 code to continually go off even after knock sensor has been replaced twice?

Is there a knock in the engine? If the motor rattles, the knock sensor will think its pinging and retard the timing to compensate. This will set the code.

What does the reduce engine power light mean?

It is an indication that the computer has detected a performance or emissions problem and has taken steps to prevent damage by not allowing the engine to rev higher than 2K - 3K RPM. There should be a check engine light on as well. You need to have the codes read to find out where the problem exists.

Check engine light , trouble code 34

Your truck is OBD2 compliant take it to a local auto parts store and have them read the code for you they usually do this as a free service, if it doesn't have a obd2 port then your truck is not a 1996 vehicle.

Sounds like misfire... Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Engine high rev at stop and slowly goes to idle speed.

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
