start with basic checks. fuel pressure, spark check. one of them will be missing and then we can focus on that system

check engine light will normally come on sometime during drive. has uaually indicated egr. not always on when car seems to overload and stop. horrible exaust or engine smell when first restarting which usually takes agout 4 or five times while coasting or stopped.
