2001 Range Rover HSE Check Engine Light

I just remove it from the vehicle, and spray the Wire as best I can from both ends, make sure that all the cleaner has drained out to help drying process...

Then I clean the connector plug with some contact cleaner and the use some de-electric grease if I have some handy.

Reinstall.

Its me again

Cleaned the MAFS again and 20 miles later I get P0734 and P0455. I know P0455 is usually something to do with the gas cap but it looked fine to me.....Maybe it was just a little off...

So you guys thing its offically time to change the MAFS? Or other symptoms I should try?

The plugs and wires look like they been changed.

Ok replaced the MAFS and I dont get the P0734 codes anymore. I get the P0455 codes still. Every 15 miles or so. I triple checked the gas cap and the purge valve.

What do you guys suggest?

Try a new gas cap?
Or anything else?

could be a bad gas cap, or you have one of the evap system line are loose or cracked...

You know all the little hoses going to the tanks and evap stuff under the hood.

Ok..On second thought I think it might be the purge valve....

I took a picture of mine. Is it supposed to be dangling out and not connected to anything?

I also noticed a little bit off the rubber of the top is peeling off. The part where the black plastic piece and the grey rubber tubing meet. Can i just tape that part?

Not the best photo.... but I am pretty sure it should be connected to something
