lexus ES 300 code p0301 p0303 p0305 fixed

this lexus was misfiring in cylinders 1-3 and 5 in rear cylinder head

[@Paryite]

I have misfire 1 3 and 5 with a lean code. would that be fuel injector ?

[@JM-AUTO]

see why you have a lean code before any thing or which codes were there first, and have you done any thing yet? if the lean came on first and soon after you got the mis then check the lean first or which ever came first.

[@Paryite]

@@JM-AUTO The lean came first and I changed all the spark plugs. new pcv valve new brake booster and i cannot find any vacuum leaks. the B1 S2 o2 sensor has voltage not on the gas but when i accelerate it goes away. It doesn’t misfire or lean on highway but does when going city speeds.

@@Paryitewhat are the error codes ?

[@Paryite]

@@assagr Just P0171 Too lean, and P0300 301 303 and 305 misfired on 1 3 and 5

[@assagr]

@@Paryite if ur saying it’s lean in city speed and maybe when going uphill, could be bad fuel pump, if not perhaps u should check air filter hoses could be a hose not installed properly, or maf sensor could be dirty.

I have a 2000 lexus es300 v6 I. just replace all spark plugs and coils without taking all those parts in 30mts.

[@JM-AUTO]

great diagnosis.

Nice informative video I have the same codes on my 2000 avalon but I think I'll take it in that looks way beyond my mechanical ability which isn't much to begin with

[@MGarage2816]

So was it the spark plugs?

[@JM-AUTO]

spark plugs and spark plug wires were the problem.

[@gennaro4941]

Don't have wires.. coils
