so here's the skinny...

93 civic: b16a swap.

when i start my car in the morning the idle fluctuates till it warms up a little bit (not even to normal operating temperatures)

the rev's drop real low if i touch the gas pedal at all and it will stall if i am reversing and go to shift into first. the battery light also turns on for a couple minutes but shuts off after i drive around a little bit.

no cel's

any ideas as to what is going on?



my buddy andy had a little captain in him. lol figured no one ever looks at threads with out pics

 

My probe Gt used to do the same **** and i hated it! it would idle at 200rpms and if i touched the gas it would stall. if i start it back up and reved the hell out of it it would seem like its getting bad miss fires and if i let it idle for about 5 minutes out of no where it would jump to 900rpm and run good. Mine turned out to be the crankshaft postion sensor. not to sure on a honda though.

doesn't seem to be misfiring, or at least i do not notice any misfiring.

 

just low idle? check your IACV or bleed your coolant system. sometimes air pockets get stuck in your IACV and cause bad idles. my friends 2000 ex idled bad till we bled the coolant system.

 

^^^^ x2. Check the timing as well

 

Since it's getting cool out, wouldn't hurt checking the battery. Especially if it's doing this on a cold start in the morning.

only for the first 2 minutes of being started is the idle low...

i was thinking maaaaybe the timing too but since the car runs fine all the time except for the first 2 minutes of being starting in the morning i dont see how that would make sense..

i will do that today after work. i was thinking maybe it could be that because of the battery light, that comes on only when its trying to die out.
