ok well the car starts fine just did some minor changes since the last time it ran



problem with the car is it stays at 1500 idle and doesn't come down even when it's warm, it's idling roughly and backfires quite a bit in neutral on deceleration and also decelerates slower then it used to



it's a n/a 87 with 10,000 KM on the engine



i have BUR9EQ plugs in all 4 but it's been like that since last october and was like that last week when i ran it



the only changes since last time it ran are I bypassed the heater core since it's fucked(coming out the engine and right to where it comes back out the firewall) and its running 89 octance when i always ran it at 87



doesn't smoke, nothing else is abnormal smells like it might be running a little richer then usual but not sure



any ideas



could it be a combination of cold plugs with 89 oct. ? could bypassing the heater core have anything to do with it?? https://www.nopistons.com/forums/pub...1047683561.gif

i think you may have an air bubble so the fast idle (thermowax) doesnt come down



mike

ok humore me but how would i fix that?

do the Throttle body mod.. and get rid of all that extra crap on the TB. also you'll get better response better.

bleed the cooling system



mike

ok i'm gonna bleed the cooling system, what's the TB mod consist of ?

There is a Topic posted in the 2nd Gen FAQ area in this forum. It's really a great mod. Cleans up the TB alot.. and increased my Throttle Response. Maybe 1 - 2 HP gain? I dunno.

ok i bled the cooling system haven't started it yet cause i know there were some other problems like rough idling and slow deceleration at idle anyone know why that might be happening??



again non of this was happening b4 today

comon guys i know one of you has the answer to this problem hidden somewhere around here...



gonna try some stuff out of the ID10T manual today see if i can correct anything



please, I'd appreaciate any input



Thanks
