Question about Cars & Trucks
The Car was was running fine the night before, but did not start right in the morning and was not running on all cylinders anymore. After some tips i changed the fuel pump and fuel filter which was not the reason why it didn't run, because the old pump was still good. the car still didn't run, so i changed the spark plugs, Spark Cable and distributor cap and checked if the distributor rotor still works which was ok, but the car still does not run on all cylinders and will shut down imediately if i don't stay on the gas. any advice?

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.

Testimonial: "right answer but I received it much too late. I went to a mechanic and paid him to fix it."
It may be the O2 sensor. I know it's not the fuel filter, spark plugs, spark plug wires, Vehicle Speed Sensor, Dis. cap, or TCM.
