LHS Stalls
 

My LHS has terrible gas mileage, low hp, and it sometimes stalls when coasting after letting off the brake. The stalling didn't happen until after I had a tune-up. Any Ideas?

I'm not sure of your model year? Did you do the tune-up? Do you think you might have left something disconnected or knocked something loose?

You might check for troublecodes? Sometimes you can get codes by cycling the ignition switch, get the dash lites to come on, no crank, on/off on/off on, thenthe cel should flash, you count the flashes to get the codes. Some of the national brand autostores will check codes for free.

its a 2000. I took it to the shop and got it done. I really don't know anything about these engines, but I suspect a vac leak, but that wouldn't contribute to poor mileage would it. Or any number of sensors. I'll see if cycling the key works, but there aren't any lights on the dash.
