stumped

I have recently experienced mechanical problems with my Saturn, it's a 1995 Saturn, SC2. five speed. I had the fuel sensor replaced along with the filter. Ran awesome for a week, then relapsed. When I start it, Idle goes up to about 2500 rpm then dies, when I can keep it running it runs great. Then my coolant fan started running all the time, even when it is cold, computer says it's too hot, gauges are fine, and temperature meeter says

190...mechanic had it for a week, and cannot figure out whats wrong??????????? any pros out there? I think my computer is going out.

It's probably a bad coolant temperature sensor. Get one from Saturn - they're cheap, and the OEM ones are less likely to have compatibility problems. The high RPM could be a vacuum leak, but any mechanic would have known to look for that so it's likely the CTS. -Rick

Sounds right. Either that or a bad contact in one of the connectors. I'd replace the coolant temp sensor and if it doesn't cure the problem, get a shop with a decent diagnostic capability. The professional scan tools (ones that we mere owners can't afford) can read out the coolant temperature. If the read temperature does not match the actual temperature, you can start tracing back.
