You have a short somewhere in the instrument cluster

These codes are not usually related. P0171 is usually due to intake leak downstream of the maf sensor. P0340 could be the sensor or the connector/harness.

try checking the connector. It is pretty common for the spade lugs that connect get corroded. Make sure there is no corrosion or clean them off and squeeze then together a little to make the connection tighter. If that does not help, verify if the high beam works or if the problem is only the LOW beam. If you have handy a multimeter, check for +12V on that connectors.

It does.

I think the Fuse melted away and is blown .

Not likely. A timing belt out of whack means the valves are no longer synchronized with the pistons and intake and exhaust are reduced in effectiveness and efficiency. Before spending that kind of money on a car that age I would have another mechanic look at it. Could turn out to be a fix that would extend the life of the car several years.

Could be bad belts in tire or tires. Pulling to right especially under load is pretty common on front wheel drives.

Sounds like it could be a similar issue to what I just went through. My car wouldn't start on two separate occasions after I had refilled my tank. First time happened a little over a month ago, the starter would crank, and crank, but no signs of life in the engine. Tested the spark plugs, I was getting spark, but the ****** wouldn't start.
Had it towed to the dealership, and they said after 4 long attempts, they got it to start. I took it home, and the next morning I couldn't start it again. Towed it back a second time, and it started right up for them. Drove it back home again and a a month later things started acting up again.
A few days ago the wife pulled the car out of the garage, where the car was level, stopped the car on our slanted driveway and when she came back to start it just minutes later, it hesitated, but did turn over. I filled up the tank and the very next morning, I could not start my car again.
Called for a tow from AAA, and the driver said "let me try something". Pulled out a hammer, and wacked the bottom of my gas tank 4 or 5 times. The tow guy gets in, tuns the ignition to engage the fuel pump (didn't turn the key all the way), he does this about 4 times, then the very next turn of the key it starts right up. The driver said it sounded like a bad fuel pump.
I drive the car back to the dealership (this is the third time) and talk to the same guy I had dealt with all along. He calls me later in the day to tell me they finally got it to not start and were able to isolate the problem to the fuel pump sensor. They replaced the fuel pump assembly and I was off and running.
Hope this helps!

code p 442 refers to Evaporative emission (EVAP) system--small leak detected ====causes -- hose connection/s intake leak--EVAP canister---EVAP canister purge valve it also refers to large leak detected ( fuel cap loose or missing====causes ---mechanical fault---hose connection---EVAP pressure sensor nothing to do with the cat converter

Check the door ajar switch that turns the radio off when you exit. Try opening the passenger door instead of driver door and see if the radio goes off, if so the switch in the driver door is defective.
