I am surging!
or maybe more of a hesitation. My old (230,000mile) lexus has begun surging between 2000 and 3000 rpm. I drove it to work this morning. Went 98% good. it hiccupped once. I took it to advance autoparts to get codes read and it was missing in drive at idle with a/c on. when rolling it struggles. it is not a solid miss. it is only sometimes.
I have checked the following:
MAF
VVT
fuel pump
replaced fuel filter
no water in the gas
i have been replacing coils as they go out
all plugs replaced a year ago
alternator and battery are good
The codes read are the following:
P0304 cyl 4 misfire
P0100 MAF (this is from me unplugging it while running)
P0110 Air temp Circuit
P1300 Igniter circuit malfunction
Any tips would be good. I am taking it to a shop on saturday. I have never been to a shop before. I would like to keep it that way.
