Customer Question

I have a 1999 Honda civic. After my car is warm up; I push on the gas and my car feels like the engine floods out. If I let up from the gas the car returns to idle. It might help if the person would know about Auto System Values from Autel scanner. Thanks, Mark

To start with have you seen the IAT reading (intake air temp) 146 deg.? This sensor read the temp. of the air taken in to the air intake Have you disconnected this sensor to see what the engine does?

Customer: replied 1 year ago.
You can see when RPM changes.. some part must be failing.
Customer: replied 1 year ago.
no I have not disconnected this sensor.
Expert:  Mastertech1 replied 1 year ago.

Keep in mind In order for the computer to send the correct injector pulse signals it relies on coolant temp. readings and intake air temps. etc.

Expert:  Mastertech1 replied 1 year ago.

Clear all codes, then disconnect iat sensor and see how it runs and send me readings with it disconnected, Thanks

Customer: replied 1 year ago.
I will try it... on Monday (12/7/2015) when I have some light to work with. Thanks
I will get back with you.
Expert:  Mastertech1 replied 1 year ago.

From the readings you have supplied,It is a bad IAT sensor or wiring to the sensor (wiring or corroded connections) Thanks

As you can see the IAT go's from (146) to (-40) when the sensor is disconnected. The same issue is present. "When my car is warm and I push on the gas it feels like the engine is being flooded out. P0113 code came up only after I pulled the IAT out and then went back to no code when I put back in. Hope this helps. Mark
Expert:  Mastertech1 replied 1 year ago.

Ok, that circuit is good, (by disconnecting the sensor,the system defaulted to -40, normal) can you send me a reading of the tps sensor with pedal depressed to about 1/4 of the way down?Thanks

Customer: replied 1 year ago.
thanks for getting back with me... I will try to get you the data on the Throttle Position sensor at the pedal 1/4 the way down

These readings are low, Try disconnecting tps sensor and see if it will try to rev-up better let me know

Customer: replied 1 year ago.
First, I will retry to get you the data on the Throttle Position sensor at a higher RPM. I feel the numbers might be lower than they should be because the pedal was not a 1/4 the way down long enough to get some good data. Second, I will disconnect TPS sensor and see if it will rev up better. Thanks
Expert:  Mastertech1 replied 12 months ago.

Thanks.

Customer: replied 12 months ago.
I took the car out and did get the RPMs up so the data might be more normal. I did not have time to un plug the TPS sensor and see if it will rev up better. ThanksHere is the live Data.

Expert:  Mastertech1 replied 12 months ago.

Tps is reading low based on the rpms and O2 reading may be caused by some old fuel in the tank, Older fuel will not burn correctly. Thanks

Customer: replied 12 months ago.
I don't know what to do. If an O2 sensor has an issue can that make an engine just stall and stop working? Thanks for trying to help me. Mark
