Driving to Manchester TN on Sunday my '97 ZJ 4.0 threw a CEL in South Western VA - it cleared by Bristol TN. Drove the rest of the way to Manchester (think Nashville), no CEL, coming back around Wytheville VA (I think the spelling is right) after filling up (for $3.189/gallon) it came back on and has persisted since. Is there a way to read the codes myself (like OBD1 where you'd read blink codes) or am I stuck going to autozone or some other retail establishment to get my codes read? Just wondering 'cause I'd like to see what's causing the code.
As an aside, I averaged 19.6MPG for the trip (around 1370 miles over 2 days) - not bad for a real vehicle with a genuine engine!
Cheers
Steve
