issue resolved thanks alot for help though guys i greatly appreciate

 

Yes, the IAT effects everything, fueling & ignition
I don't know how your tuner continued tuning your car with a bad iat sensor & with a malfunction indication code being thrown...

 

big difference.. i forgot what iat value the ecu defaults to if it doesnt see the sensor but it will affect your tune.

 

Can't answer that question as I have no idea what condition the car was in while it was being tuned & now etc...

The IAT readings would have been totally off while he was tuning the car.... there is no excuse to have tuned the car with a faulty IAT sensor.

If the car was throwing an iacv code, he should have resolved the issue as well.
There is no reason to tune a car that is throwing a code...

 

i'd like to know who this tuner is...
most of the guys near me wont tune your car if it doesnt have a full exhaust (no open downpipe) much less throwing codes and not running right (regardless of the tune)

 

123F I think on Hondata. Which is pretty close to what you will see at this time of year in Georgia. I *think* you said it was throwing an IACV code while you tuned, not a IAT? IACV code is not really a show-stopper like the IAT is.

As for the partial throttle bucking.... hard to say what that is. Usually happens because of lean misfire. That would be in the tune/fuel maps.

 

If the IAT sensor was melted. it's because you had the connector for the purge solenoid plugged there and the IAT plugged into the purge. This will instantly melt Q31 on the ECU.

 

Yes you shouldn't tune your car with check engine light. Especially iat it affects ignition and fuel. Who's your tuner?
