All right . Full tune up down. Cap, rotor, plugs, and wires.
No improvement or change.
However just before buying tune up parts . The car threw a CEL with 2 codes. P0301 and a P1399.the first was a cylinder 1 misfire and the other said random misfire all cylinders.
So what could cause misfires in only the lower rpm ranges under load but none 4k and above under load.

Any ideas on what it could be outside of a tune up and the timing belt?
Strikes me strange that it is only in that rpm range and not throwing a cel or code.Any ideas on what it could be outside of a tune up and the timing belt?
Strikes me strange that it is only in that rpm range and not throwing a cel or code.I bought the car with 60000 miles on it. It now has 93,000 to my knowledge the timing belt has not been replaced.
It will be getting done at the end of January when I get back from leave.I bought the car with 60000 miles on it. It now has 93,000 to my knowledge the timing belt has not been replaced.
