To clarify, code 171 is for the O2 sensor signal being too lean, but code 301 is for no power on cylinder one.Since both codes could be from low fuel pressure I would check that first. Its possible the O2 sensor is faulty so checking that with a scanner is the normal action to take. Its also possible the injector for cylinder one is worn out. Fixing one code may take care of the other code.

Here's a link to your belt.

The 1,2,3,4 preset buttons on your radio toggle up only through the digits 0-9. The 1 preset button is the first digit holder, and so on for the 4 digit code. If you go too far just keep pressing the button, and it will go back to 0, and you can get back to the right number. If your unlock code has a 0 in it you have to press the button once to get to 0. It starts with a dash (-). This doesn't count as the 0. For instance if your unlock code is 0873, you will press preset 1 once, preset 2 9x, preset 3 8x, and preset 4 4x. Once you have the correct number in the display press the "CD" button, and it will unlock your radio. If you didn't do it right, it will display "ERR1" before going back to the "CODE" display. Don't mess up more than twice. After the third failed try things get a lot more complicated. Good Luck Tim

Is the check engine light on?

Wow, The throttle cable will be the next ground the system would find if it lost the main ground. It would be too small to carry the load and melt the plastic to the cable. Have to change that part.Make sure the ground from the battery is good to the engine,AND the body.If the engine doesn't have a good ground to the battery the throttle cable will take the load if the body ground is good. There should be a smaller ground that runs to the body somewhere,doesn't matter where,Also if the throttle is stuck wide open there will be no fuel allowedto the motor. Made that way so if it gets flooded, wide open is a "clear flood "mode.

Check throttler pedal and cable for stuck position

sounds like the brake light switch is stuck the switch is on the brake pedal when you push the pedal to apply brakes it completes a normally open circuit

dealing with timing chains its harder then timing belts i mean if you have the right tools it can be done but it can be pretty difficult when dealing with the timing , and the chance of a bent valves it depends if you have a 2.0L DOHC there is definatelly a pretty good chance that u might have valve or piston damage, if you have 2.0 SOHC u wont have damage at all

The crank sensor gets power from the MFI relay just like the injectors and cam sensor do.

I had this problem and fixed it easily. It sounds like the turn signal mechanism is broken. Fortunately, the turn signal/headlight lever is a distinct separate unit that can easily be removed from the steering wheel assembly, remove 2 screws and the 2 eclictral plugs and it comes right off. Then get a new one at autostore for ~$80 or pull one off any 2g eclipse at the salvage yard for cheaper, better option and you should be back to signaling your intended turning direction in no time.

check to see if ur getting power to the small wire that triggers the starter solenoid also check battery cables positive and negative make sure starter is grounded good

its probably the Idle air motor. they always go bad on the 4g63.

rpms should be about 750, or 850 with the A/C on

Check out the fuse for the convertable top motors. See if something is binding against the convertible machine motors or mechanisms or the material itself. Pull it up slightly to free any obstructions and try again. If you can, check to see if the relays for the vtop motors are working and see if you are getting power to all devices including the switckh on the dashboard.

The po301 is a misfire code. The backfire can be caused by a excessive amount of fuel, bad valve timing etc.
My guess is you have damage to an exhaust valve that may have occurred when you had the timing belt problem.A compression test will indicate if you have a leaking exhaust valve.The reason for the backfire is the exhaust valve is still partially open when the spark plug fires.

DUDE you cracke your engine block or an exream head gasket failure time to replace the engine Johnie G ASE Master 35 yrs
