There could be several problems. The aux air valve is closing too soon or the head temp sensor is losing resistance too soon. Sometimes the factory put a spacer in the temp sensor hole to isolate it so that it would stay in high resistance longer and thus provide more cold enrichment. Also these days with old injection components and leaking vacuum, we have contributory problems.
Please remember that the cold start valve is for initial startup only and for 1.7 and 2.0 models only functions in the crank position AND at 40 degrees or below. The 1.8 functions the same but at 60 degrees f or below. if its close to, or above freezing i was thinking of starting up 70 1.7 d jet once in a while, and letting it idle/warm up for a few minutes.any opinions / facts on this.plus i have a cold start issue i would like to address.on start up the car idles for about a minute then i have to keep it running till she warms up about 10-15 min. of driving.once warm she idles nicely at about 850 rpm.
