What if you still have the same symptoms after changing your catalyic converter?
Well . . . you know the problem was not caused by a bad catalytic converter. You could experiment with replacing your oxygen sensors, next . . .
What is the cost to fix the electric sensors in a car?
That all depends what sensors need replacing
Where is coolant temp sensor located on a hhr?
Coolant temperature sensors are usually located on the radiator.
How many coolant temp sensors on a 97expedition 4.6?
one
Why wont 2001 Chevy Impala start after replacing the thermostat?
If a 2001 Chevy Impala will not start after replacing a thermostat, perhaps it is possible that a sensor was bumped unknowingly. Check all of the sensors that might have been touched during the changing of the thermostat to see that they are all still plugged in.
What else can you check for an erratic idle on a 2004 Nissan Altima after replacing both the crankshaft and the camshaft positioning sensors?
It could be a dirty mass air flow sensor located between the air filter and motor. Only use mass air flow sensor cleaner to clean it.

Why do you keep getting a coolant sensor trouble code after changing the sensor and clearing codes on a 1991 gmc sierra 5.7?
Check to see if your 5.7 has 2 coolant sensors---if it does they should be on the front of the engine on the intake manifold and on the cylinder head, usually on the driver side close to the exhaust manifold.
When the acura is running the RP Ms are jumping all over the place then the car dies?
I don't kknow what acura you have but on my 1990 integra gs low coolant level will cause the erratic rpm. Also the intake manifold gasket could be leaking causing an erratic rpm condition check all your sensors, mostly the throttle position sensor (on the throttle body) also check to make sure you dont have any vacuum leaks.
I have 95 z28 camaro the gauge it is over heating but its not i have replaced the water pump hose's temp sensor and temp sending unit could it be the gauge or something eles?
It is possible it's the gauge. However, if you used Duralast sensors, or the cheap version of any sensor, that could be your problem. I have had similar problems for months with my car. While replacing intake gaskets I replaced the coolant sensor and coolant switch because they were easier to get to at that point. I thought I was taking preventative measures by replacing them then. Couldn't figure it out. I recently got some factory sensors and tested them against the Duralast brand. There was quite a bit of difference. I replaced all my new sensors with some old factory sensors and it's working fine now. They cost more, but when you can, go with AC Delco on the sensors. BWD isn't too bad and Standard is decent too. I'd bet that is your problem.
Will changing your O2 sensors get rid of my rough idle?
Before you change the 02 sensors, make sure the problem is not a faulty hose leak. I was having the same problem with my 98 Expedition (Eddie Bauer) and the diagnostic codes indicated that all 4 of my 02 sensors needed to be changed. Thanks to an honest mechanic, the problem was solved by replacing the vacuum hose for under 20 bucks.
Should you disconnect the battery when changing the speed sensors on a transmisssion?
