I put 2,720.00 worth of work into my 97 Pontiac grand am. Engine light is flashing the car sputters and might get up to 40 mile per hour I took it out on the road again and got it up to 75 mile per hour...


Sounds like who ever did the work on your car needs to go back and check the plug wires to see if they are going to the right plugs. and check the fuel filter, and fuel pump pressure. I would also check the Catalytic Converter to see if it is stopped up, if so replace it. Check the throttle position sensor with an ohm meter, if bad replace it. Check the oxygen sensors as well. I am running out of Ideas, so I hope this helps.

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

2000 E-350 V-10. P0174 with exhaust fix


Before I even finished reading this i knew you had a clogged cat. If you have fixed everything you mentioned i would lean towards a clogged cat. This is a large reason this code pops up.

To check this you could pull that cat out and drive around and see if the code comes back, make sure to stay away from the police though.

Engine light on


A code P0420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of readings
  • That should get you going.
