SOURCE: 94 camry. 2.2 fed emissions.

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.

My Opel corsa Lite 1.4i, 2005 model cuts off when idling or stopping. I've replace the ignition coil as it was suggested but the next day the problem continued. I've replace plugs, filters, ect. When I'm approaching a place where i have to stop i see lights on dashboard coming out and the engine goes off if i stop or if i put the second gear it kicks again. Please assist as none of mechanics in my area know where to fix now.

High engine Idle

Find out what the trouble codes are before you replace anything.
I would disconnect the idle air control valve when the idle speed is around 1200 and see if the idle speed stays or continues to climb.
if it climbs with the valve unplugged, you have a vac leak somewhere, probably the intake gasket.

What would cause engine stall when parked or idle with ac on?

I take it that you recently had the battery disconnected or replaced? If so, easy $4 fix for a bottle of sensor safe throttle body cleaner. It's your dirty throttle body which is very common for our trucks. Your computer learned some bad habits, so when you hooked the battery back up, it thought the throttle body was functioning properly.

Unhook the battery again. Take the plastic resonator off the top of the engine. Remove the hoses and unhook the electrical connectors. Unbolt the throttle body (4 bolts), carefull, don't let them fall down by the intake, hard to find, so keep a magnet near by (been there done that). Remove the electrical connector from the throttle body. Need the spray bottle of cleaner ( I like Seafoam spray) and drench everything. Can use a toothbrush for some elbow grease, take your time and make sure it's nice and shiny. Hook everything back up, then hook your battery back up. Drive around for 20 minutes or so with all accessories off so the computer can re-learn a properly functioning throttle body. This will fix your problem and should take 30 to 60 minutes to do yourself. Look forward to better gas mileage and better throttle response when clean. Throttle body should be cleaned at least once a year, because we don't have a traditional PCV valve, so our TB tends to gum up fast.

I replaced the coolant temp sensor and the map sensor in my 2003 GMC Envoy truck (with the battery disconnected for 3 hours) now when the AC is turned on ( at idel) the truck turns off. Any help you can...

Did you clean the throttle body while you were in there? If not, that's your problem. When you hooked the battery back up, the computer thought the throttle body was functioning properly. Learned some bad habits before. Disconnect your battery again. Unhook the plastic resonator on the top along with the hoses that connect to the throttle body. Take the 4 bolts off the throttle body and remove it. No need to worry about a gasket, just has a rubber O ring that is re-useable. Clean with plastic bristle brush and throttle body cleaner safe for sensors. Clean that pupply til it's nice and shiny. When done, connect everything back up, and drive around for 5 miles or so with all accessories off. This way your computer will relearn the properly functioning throttle body. Problem fixed and $4 spent to fix it for the can of cleaner. You'll notice a world a difference in your engines performance. You should clean this at least once a year.

either the idle air controller is malfunctioning or the Throttle position is-both are located next to each other on the back (firewall) side of the throttle body. If you remove the air tube from the air leaner, you can remove he throttle body:rotate the throttle bell crank and push the throttle cable out of the crank slot. Unbolt the throttle body (4-12mm bolts I think) and pull the throttle body enough that you can unplug the harnesses. The torx screws that hold the IAC and TPS can now be easily be removed. Clean everything with THROTTLE BODY CLEANER, and do a thorough job-especially the IAC, being careful not to spray the top half becasue it contains electronics that will not like being doused with any fluids. The TPS rarely shows lots of carbon buildup, but since you are there, check it out anyway.

All of this is assuming you do not have a check engine light-your problem is common on these cars and you should also replace the engine coolant sensor regularly on these cars, and the thermostat if the temp gauge is less than 1/4. I have one of these with 178,000 miles, they are great are but need some routine maintenance and a clean throttle body to run properly.

Throttle position switch. how much for the part? is it easy to repllace?

This sensor sends the ECU an output signal which corresponds to the opening of the throttle valve. Using this output signal, the ECU precisely controls the air/fuel ratio during acceleration, deceleration and idling. The TP sensor and the throttle switch are combined as part of an assembly. The switch signal turns ON only when the throttle is opened to the idle position or at Wide Open Throttle (WOT) acceleration.

( see Figures 2, 3, 4 and 5 )


Fig. 2: Disconnect the wire harness from the throttle position sensor-Legacy


Fig. 3: Paint a matchmark on the sensor and throttle body for ease of installation and adjustment


Fig. 4: Remove the sensor retainer screws


Fig. 5: Lift off the throttle position sensor
  1. Disconnect the negative battery cable.
  2. Disconnect the throttle sensor electrical harness.
  3. Place a matchmark on the throttle position sensor and throttle body mounting surface, so that during installation, the sensor can be properly aligned.
  4. Remove the 2 screws securing the throttle sensor to the throttle body assembly.
  5. Remove the throttle sensor by pulling it in the axial direction of the throttle shaft.
  6. Remove the throttle sensor O-ring and discard.
To install:
  1. Using a new throttle O-ring, install the throttle sensor, aligning the matchmarks. Install and hand-tighten the retainer screw.
  2. Connect the throttle sensor electrical harness.
  3. Connect the negative battery cable.

Hope this help (remember rated and comment this). Good luck.
