Lumina won't start after being driven for a while then parked.
After driving back from a work location, roughly a 45 minute drive, my '99 Lumina wont
start again for around an hour after parking it. It was throwing misfire codes and EGR
codes. I've replaced the EGR, cleaned the channel from the EGR to the throttle body,
replaced plugs and wires, replaced O2 sensors. It no longer throws any codes, but the
issue persists.
On initial start it will idle normally, drop then come back to normal. It repeats this
pattern, though some days it is more noticeable than others.
With no service engine light on and no codes being thrown I'm not sure where to look
next.
