Hi,

I've got a '90 Civic Si HB with the '89 ZC engine/trans and '89 'teg ECU. After some teething problems caused by a bad distributor I've got it running generally ok, with one major hiccup.

Every so often when sitting with the car in neutral the idle will jump from ~800 rpm to 2500... then 3500.. 2500... 3500... 2500....

Sometimes if the wind is right I can smell that it's running waaaaay rich.

And sometimes it'll keep doing it, and other times it'll kick on the check engine light and give me an error code "6" (temperature sensor).

I've been reading the factory manuals (I've got the USDM manual and the pdf of the UK CRX manual) and I guess I've figured out what to check with the 2 pin temp sensor underneath the distributor. If it is bad... will a USDM Civic sensor be the same? Or do I look for an Integra sensor?


TIA

make sure it is completely full of coolant and that there is no air in the cooling system - bleed the air out
