Had a strange problem pop up today; '88 turbowagon- running great, I pull in for gas, fill tank, jump back in, no start.
Cranks over, spark is good, (plus new cap and rotor) -finally after 20 min it started, but runs very rough now. Check engine light on intermittant; fault code 21- which I believe is coolant temp sensor.
Anyone seen a bad temp sensor cause rough idle like this?
