818sc400

Sup all,

Last week my car started acting up. It would bog off the line up until freeway speeds. It really hesitates going uphill at around 50 mph. Also at idle the car has "mini backfires" and shakes a little.

I never had a tune up since i owned the car so i decided to get one today. They replaced Caps,Rotors,Wires,Plugs. the car seems to be misfiring and smells like gas comming out from the exhaust

Unfortunatley the problem still exist. Anyone have any ideas what can be wrong? theres no cel codes.

car is 1995 sc400. 187,xxx miles. been running like a champ till last week. ive owned it since 2005 and it had 147,xxx when i bought it
