Last week it started not wanting to turn over as easily as normal but then started working fine again. This morning I took my daughter to work and on the way home at a stop light it started idling really rough. I had to go back out to the bank and on the way there the service engine light came on. It went thru about a quarter tank of gas in maybe 7 miles. Any ideas?

Welcome to the forum. Have your trouble codes checked. Some of the national brand autostores will check codes for free. Because 95 can be a crossover year between obd 1 and obd 11, I don't know if the autostore can check them, but, you can ask.

How long since a tune-up? Fuel pressure good? Are you TBI fuel injection or CPI?
