    Did some research and the link is the best description of that system I found but doesn’t apply specifically to your Trooper. I also don’t like dumping a vehicle for little reason and that quote of nearly $1600 is suspicious. I would obtain a manual (eBay) in any form; most offered there are .PDF files on DVD more reasonable in price but less convenient to use. I also think replacing the gas cap would be my first move since any fault in the closed system may trigger that code. The linked page lists the possible sources of P0446 and one of them is the canister that traps fumes. If it or any other part of the fuel system isn‘t tight, that code will appear, Good luck and if you find the cause of the problem, do us all a favor and comment back to this thread so others may benefit from your efforts,

    Not knowing where you live, I am not certain the following suggestion: If you live near a larger high school. check if they have an automotive shop program; in my experience, the cost is very low and the instructor is someone with a raft of knowledge, the info and equipment are often extensive. It sounds as if you cannot deal with this hands on, this may be a way to save most of that ~$1600 which sounds excessive to me. Good luck-

Oil light is on but full of oil

the red oil light is on? if so you may have a faulty oil pressure sending unit or you have lost oil pressure. best way to check this is by installing a mechnical gauge on engine and seeing what pressure it is reading. if it is low oil light on then the low oil level sensor is defective

Oil light on engine is full of oil

HI, The Oil Light comes on to show a low oil pressure not just that it is low on oil. If your not experience any unusual engine noise i would not suspect low oil pressure but more likely a bad oil pressure sending unit.

I have a 2003 Mercury Mountaineer V6 AWD. Check Engine Light came on - brought it to the dealer and they said the code was to replace the solenoid. Had that replaced and after driving it away, light came...

Replace what solenoid specifically? What was the trouble code? Most parts stores will pull OBD-2 codes for you for free and give you a brief description of what they mean. I would try that then come back here.

Oil light flashes on and off!!!

It would be wise to replace the sending unit, but that might not be the problem. The only sure way to tell is to put a manual oil guage on it to check the oil pressure

Sluggish engine

Could be your catalytic converter. Get an Oil Change and see if they will read your codes. If it indicates misfire or exhaust problem have the converter replaced. DO Not pay 600 dollars buy an after market converter and let them weld it in. Should cost 200 -300 bucks.
