Car Forum / Honda Cars / February 2005IDLE FLUXUATIONS 1990 HONDA CIVIC 1.5 L
My honda on a cold start idle fine. When it warms up it start fluxuating drastically @ 1000 to 1500 rpm. I was told it was a throttle body sensor and that you had to buy the whole throttle body to get the sensor for that year. Need help. thanks, steve FITV or IAC needs cleaning. I have 2 complete 1.5L DPFI setups if you figure out what parts you need. > My honda on a cold start idle fine. When it warms up it start fluxuating > drastically @ 1000 to 1500 rpm.

Need help. thanks, steve double check the coolant level in the radiator [not the expansion bottle]. insufficient coolant sends the wrong temp sensor signal to the ecu & it goes into cold idle mode until the revs rise enough to bathe the sensor. than it drops & the cycle repeats. |
