Grand Prix, Cold Start Problem
Q: I have a cold start problem and I've had it checked out
and they can't find the problem. They think it's the EGR valve which is
$250 and I can't see replacing it for that much money with it only being
a guess, what should I do?
can't see why you need the EGR valve in the first place. The only way
an EGR (Exhaust Gas Recirculation) valve could cause a cold start problem
is if it was causing a warm running problem as well. The EGR valve remains
closed while an engine is being started and in most vehicles does not
function until the engine has warmed to a specified temperature. The best
deal for you would be a second opinion.
