Try cleaning the inside of the MAF sensor, the throttle valve and the idle speed control valve, then disconnect the battery for 5 minutes and drive for a day or two, this should correct the problem or make it better.

Is the wiring good going to the O2 sensors? Maybe just look the car over and see if you have any bad grounds. They can do weird things. Could be a bad ICU.

Rough idle and stalling.did full tune up no change.changed o2 sensor ran like a dream for 2 days then started running rough and stalling again so i changed o2 sensor again and it ran good for 5 minuets...


the engine is emitting more carbon than the exhaust can transfer out befor cloging the o2 sensor
can rebuild the engine. not to confirm this simply pull the o2 back out take brake parts cleaner and spray it let air dry then reinstall and if it does it agine you know the engine needs rebuilt

94 camry. 2.2 fed emissions. Rough idle. runs great any rpm off idle. have checked timing. vacuum leaks, plugs, spark, removed throttle body and iac and cleaned. removed egr. plugged intake. all with no...


Before we both knock ourselves out with fuel injector testing. Hook up a Digital voltmeter (DVM) to upstream O2 sensor and lets see how she is burning. Remember positive lead of DVM to signal wire and negative lead to ground. Anything above 550 mV is rich anything below 350mV is lean. Be mindful that an exhaust leak the size of a pin hole in this region can cause a rough idle. A healthy reading should bounce between 550mV and 350 mV.
Next to test is O2 is working block off air in take making mixture rich and see what O2 says about it . Then pull off a vacuum hose (a lean condition) and see if DVM drops to 200to 300mV's.
Keep me posted.

Check the DIS module or injectors. Check to make sure you have a spark on each cylinder. One cylinder could be misfiring

P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L


Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)

Code 1131= upstream; bank 1..sensor 1
Code 1151= upstream; bank 2..sensor 1
Code P0136 (generic code) bank 1..sensor 2 (questionable)

I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea.
Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.


Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read
open or a high resistance run two straps from eng. to body...and body to neg.batt. post.

it sounds to me that the sensor your talking about is the camshaft positioning sensor. It regulates how much fuel you get to your engine, so that is also why you have the fuel smell as well.

It sounds like you may have a broken exhaust valve spring, although, like you have found out problems like this can be very hard to diagnose, but anyone with a compression tester and couple other tools could find out if this is the case. Hope this gives you another idea where to look.
