Could someone tell me what 02 sensors to buy and which 0 2 sensors go where?
I am pretty confident I can change them myself I just want to make sure I put the correct ones in the correct places?

Do i need a torque wrench to install them properly?
Do i just need to buy two front and two rear 02 sensors?(are there left and right ones?)

Should I put a cleaning agent in the gas tank?

 

Only buy a Bosch MAF. I tried cleaning (died in three days) and a aftermarket (continued to get codes). As far as 02's, you need to replace your MAF, clear you codes and then see if your 02's are OK. MAF needs to be ASAP because if bad it can kill perfectly good 02's. Your gonna need a torque wrench at some point. Get a inexpensive OBD2 code reade so you can read and clear codes. 38 bucks at autozone. I keep mine in my truck.

 

where do you hook up the code reader at?

 

I found one on BPUTAH for $145(Bosch),do I need the O-ring too?

 

The MAF should come with the O ring, but yes you do. The reader hooks up under the dash on the drivers side. You will see the connection and don't need to remove anything like interior panels.. Good luck. Those 02's are expensive and I would clear you problems one at a time.

 

I cleaned the plastic housing of the MAF(inside and out) and hooked up the code scanner and reset the codes and the service engine soon light has gone away,lets see if it stays away for awhile.
It looked pretty new,the previous owner did a lot of the work himself on the rig , so maybe he never reset the codes.

 

It will take a little time to go through a drive cycle but you can check your code reader after a day or so even if your light is not on and you will get pending codes if you have any. Hope they are gone. Also check and make sure the filter cover and all the tube that runs to the upper intake is nice and tight.

 

Light came back on,but with only 5 codes:
po174
po171
p1175
p1172
p0734
so po733 is now gone.

 

Just ordered a new Bosch MAF $142.78 shipped.

 

Great..install (5 minutes) and clear your codes and good luck. Think you will be okay.
