Does anyone know of what might be causing this issue - I have a 95 sc300 with 157k miles. The problem started yesterday when we experience a sand/dust storm in Dallas, TX blown in from west Texas.
When I push on the gas pedal, it hesitates a bit and then moves on. When you put in reverse, I get rough idle while moving back. I changed the air filter as it was dirty but don't know if it's the cat, spark plugs, injector, fuel filter or what.
This was not happening in the morning and only after the storm got worse
