im not sure

kwikb16a2 11-Mar-2004 05:40 PM

check for vacuum leaks

imported_fine2ne 11-Mar-2004 05:40 PM

could be crappy gas, mine did that on one tank of gas that i got somewhere in newmarket. I filled up after that and the problem went away. Maybe add some octane booster if you filled up at a crappy gas station.

kwikb16a2 11-Mar-2004 05:45 PM

do a TCC search, this problem comes up allot, there are many threads on this topic,

kwikb16a2 11-Mar-2004 05:51 PM

hmm i say check out the vacuum hoses, all the rubber hoses from the brake booster, pcv valve, Evap, map sensor, cruise if u have it.

thanx for all your help guys!

spracingsports 11-Mar-2004 06:06 PM

ya get a haynes or chilton...

BTW, how much do there run for and do they have them at bookstores like barnes and noble, or can i get them through a honda dealership?

imported_Old_skool4g 11-Mar-2004 06:17 PM

yah i got dat problem too....could it be the IAC?

kwikb16a2 11-Mar-2004 08:11 PM

i think the IAC is responsible for only cold start up, but im not 100% sure, the helms can be had at the dealer but costs a pretty penny. Chilton and Haynes are cheap

bbarbulo 11-Mar-2004 08:12 PM

OH mon dieux

you are low on coolant or have air in the coolant lines

vacuum leak

bad IACV

bad high idle sensor (aka coolant temp sensor :p )

PEACE!
