Question about 1994 Honda Civic
This is easy,, it can be 1 or 2 problems.
1: CAT is dead or weak, new cats can in fact hide a crappy engine.
2: bad engine. runs like junk and does not burn all its fuel.
any good shop can find this is minutes.
what I DO (no 5gas mach)
i check for (scan tool costing me $9 whole bucks) ask)
i check for closed loop status, idling
if ok then at 15mph and then 25mph , just racing motor in neutral.
if all 3 tests pass, im good.
if any fail, i fix that. bad fueling, bad spark or whatever.
if all 3 pass, its NEW CAT TIME
easy huh? a binary answer.
bad cat, bad motor. (or both)
when i say bad motor that means,every inch of the EFI/engine system.
