CEL Codes

just purchased my own OBD2 scan tool....innova3130, over 60% off of list price couldn't resist

here are my codes

P0305 - CYLINDER 5 MISFIRE
P0174 - SYSTEM TO LEAN (BANK 2)
P0306 - CYLINDER 6 MISFIRE
P1288 - CYLINDER HEAD TEMP OUT OF SELF TEST RANGE
P1464 - A/C DEMAND OUT OF SELF TEST RANGE.

i have replaced all the plugs bought from the dealer, now i am thinking the misfires are due to the coil packs

any other ideas ... please list them...

I picked up the 3160 earlier this year off of Amazon.com for a sweet price. I've got a websight that will give you a good deal of knowledge on obdII codes: http://www.obd-codes.com/trouble_codes/. Hope that helps.

For technical assistance, you need to provide the year, model, engine, and other specifics for your vehicle. We are not psychic.

Also, please do not start a new thread for for each question you have on an on-going issue or project... Keep everything in one place.

It is very hard to follow you....you're in 10 threads on various topics and now you are mixing your questions and responses among them.

Starting at the bottom:

When you scan the engine, you should have the HVAC system turned off.
And the engine should be at normal operating temperature.

You probably have a small vacuum leak on bank 2, which may be causing the misfires on that bank.

Can your scan tool pull up the 'freeze frame' data?
