Any warning lights come on during the drive - check engine/service engine soon light, oil pressure light, etc
Check engine light was on prior, ,but no issues until yesterday 's high speed drive. FYI . I changed oil filter and checked all levels prior to trip.
It was the last 3 miles where it got progressively worse. Give me any possibilities. Thank you.
Ps.. could I have fouled plugs?
Possible causes are fouled plugs, faulty coils(check for oil on them as I see this quite a bit due to leaking spark plug tube oil seals), faulty fuel pump, vacuum or air intake leak, or clogged/restricted catalytic converter.
