Pulled in the driveway last night, parked. Car was running great. This morning, started car to warm it up (28F this morning) got in 15 min later and pulled out of driveway. car was OK for about 100 feet, then began to loose power, almost as if running out of gas. Bought some injector cleaner and added it to an already full tank of name brand gas. Car starts and idles OK, just will not pull itself down the road. Before I let the mechanic go on an "easter egg hunt", where do I look? MAP sensor? Fuel filter? Vacuum leak?
