2002 taurus SEL-5 engine codes to go with light and problems

I have an 02 taurus DOHC engine. I had codes run and got 5 back. They are P0136, P0141, P0303, P0316, P0302. They came with descriptions saying that cylinders 2 and 3 have misfires, and heated oxygen sensor bank sensor 2 is defective.  and that Crank sensor is defective. Where do i start to look for parts in to replace to get this back to normal and get the engine light off?

Cylinders 2, 3 have coil packs change out located on back of motor. you will have to take the upper intake off to get to them. Very easy to do. #2 center plug on back of motor #3 is on drivers side of motor. Crank sensor you will have to remove tire on car passenager side next look at crank pulley on left side of block you will se two wires the heat cover running to it.
Change these first it might correct the O2 sensor problem.

I have a 2003 Dodge Stratus Coupe R/T. Just got it inspected and it failed. Check engine light is on and the codes it failed for are P0136, P0141 and P0456. Pep Boys told me I have to take it to the...

You have to realize that vehicle is15 years old and probably worth peanuts. if you repair it then a few weeks later it breaks down again you have probably wasted your money. i feel to repair it you will pay close to a thousand dollars then you don't know if it will pass a safety next year
I would scrap it and get a good one. Just to go to a dealer for a check up will cost over a hundred dollars.

97 eclipse p1105, p0443, p0141, p0136

Unfortunetely none of those codes will be related! Is this car a manual trans? Seen some clutch switches go bad.. But either way double check the starter relay and even try swapping it with another one in the under hood fuse block... Depending on where you live I have found ants love to get there *** into the relay boxes for some **** reason...and they will short the heck out of em!, But the codes your pulling will not be the reason for the clicking,02 effects how it runs, fuel metering also, evap is for emissions only..

Code p0141 on ford Taurus 2003 dohc stalling randomly on cold start. warms up and drives fine. already replaced that senor. replaced plugs , wires, fuel filter, put fuel treatment, cleaned throttle body....

That code is for 02 heater circuit. Replacing the sensor may not fix it. I'd have to check voltage and ground for the heater circuit wiring. The voltage is fuse protected, red wire.

Check engine light is on 2002 taurus SEL DOHC

it could have been running bad with the bad plugs. reset the computer and see if the light comes back on. you may have already fixed it. to reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer.
