Hello there, namesa whitey, I have the 93 mark with oversized injectors custom intake, custom exhaust. Glad to know there are other fellow people just like me. Any info about a rough running mark would be helpful, car shakes at stop @ idle. dont have the power it did. can hear it in the exhaust.
Hello all new to this forum but I love my mark

hey Whitey, i got your pm. welcome.
did this problem start before our after the mods you listed?
exhaust doesn't usually cause this problem, but an intake issue can.
why the oversized injectors? unless compensated for with a tune, they can present more problems than its worth. and 28 pound injectors are just fine for a stock or lightly modded car.
what's the mileage?
any info on the car's history?
any major repairs done to it?
any relevant info you can think of?
you may have a vac leak.
you might need spark plugs, or plug wires.
you could be low on fuel pressure.
lots of variables here.
