Sierra doesn't quite run right. any ideas?
This is a 1994 Sierra, has a G13BA engine installed. usually runs like a dream and gives very few problems. About three weeks ago the engine revs seemed to be a tad higher than normal, additionally the engine has now developed "running on" after the ignition has been turned off.
Things I have checked:-
Vacuum hoses associated with environmental stuff I assume, plus timing advance etc etc, (thousands of them, replaced them all)
Replaced the air filter
Choke seems to be working but maybe not as well as it should do, not sure.
Any ideas? Thanks for any assistance rendered.
