When you say throttle damper, you mean the device which stops the throttle from slamming shut, right up by the throttle actuator? > Just went out to check it out, > and if I leave it to reach operarting temp, it idles rough (erring on the > side of slow rather than fast), sounds a touch unhealthy, and I'm getting > quite a lot of white smoke coming out of the exhaust at that stage. Hm, white smoke is bad; coolant in the combustion chambers. Has the car ever run low on coolant that could explain a head or head gasket problem? A compression test is probably in order. > Any ideas? It's a 1988 900 T16S. Rough running without the white smoke, I'd suspect they knocked a vacuum hose lose when they did the dashpot, but the white smoke sounds like a head or head gasket problem. Most likely unrelated to the work they just did, I'm afraid. Dave Hinz
