Asked by Sep 28, 2015 at 06:38 PM about the 1998 Lexus ES 300 Base

Question type: Maintenance & Repair

,  Check engine keeps coming on every 100 miles or so,. Sometimes i fill
up with premium gas and add fuel injector cleaner and the check engine
will go off for a tankful or 2 then come on again. Don't remember code but
1 thing the code defined was mass flow sensor, oxygen sensor and 1 bank
misfire (the 3 cylinders closer to firewall getting to much fuel) What could it
really be wrong?

Post the codes here but in the meantime start with the misfire code. Do you remember when the spark plugs were last changed? Might be the spark plugs, wires or the coil. That might clear up the MAF and O2 codes.

I bought car 2 years ago, and I have not changed plugs, or spark plug wires or coils . car has about 120 k miles. The car runs good . sometimes will not crank on initial start up , have to try 2 or 3 turns of the key. I have changed the fuel filter.
