Rodeo engine code interpretation??

[joefear7]

ok so I followed Indys advice and went to Autozone and with a OBDII scantool, pulled the engine codes. The engine runs crappy and this is what it said:

P0155 O2 sensor heater circut malfunction (bank 2 sensor 1).
P0300 Random/multiple cylinder misfire detected
P1441 Manufacture control auxilary emission control

It also told me that when it was running that the HO2 sensor was ready but the o2 sensor was not ready or working or something.

Can you guys help me figure out what the heck is going on??

The P0300 code is making me lean even more heavily toward you having a bad IMG (intake manifold gasket). That problem can cause weird O2 related readings as well as the misfire. But, on the other side of the 'chicken or egg' battle is that a bad O2 will cause the vehicle to run oddly.

***do this at your own risk*** You can take some carb cleaner and carefully spray it around the intake manifold while listening to the engine idle. A change in idle speed would indicate a leak in that area.

I'm banking on IMG... but let us know what you find:D

BTW... when you make a follow-up post like this its generally better to put it in the original post versus making a whole new thread. Makes things nicer for people using the search feature later on... assuming you even care:flipoff2:

[joefear7]

so which side is bank one and which is bank two? passenger or driver?

[Canucklehead]

Passenger's side = Bank 1
Driver's side = Bank 2
