My car has does NOT like to stay running. My IACV was leaking coolant a few days ago, bought an OEM IACV from Honda for $190. From a cold start, it starts right up & ides perfect, then when i rev it up past 4,000 RPM, then it falls past idle & stalls. After its good & warm, it starts up but drops below idle & stalls. Then after i got on it, it stalled going 45-mph, had to re-start it & keep my foot on the gas. WTF?

Should i look for something in my map? or what should i do?

 

Does it always start right up after stalling, with no problems?
If it does start up fine, then i would suggest something with your MAP setup, as mine was doing a similar thing. I was running a VTEC-AFC for monitoring , and it was giving false readings, causing it to stall. Fixed the problem and haven't had any trouble yet!
Good Luck!

 

yeah, it starts right up, but i have to keep my foot on the gas at all times to prevent stalling.

 

So...... i need to check my GM 3-Bar Map sensor? or my AEM MAP?

Any other ideas?

 

try replacing the coil

 

Distributor & starter are both NEW
