Take it back to the garage and complain! I would if the shop owner didnt passaway 10 days ago. God Bless.(shop closed) Sorry to hear that. You could drive the vehicle to your local auto parts store and have them read the codes set in the ecm. The codes should help you determine why the engine is running poorly.
Some are lazy, slugish, drowsy, and dull .
yes it would become very slugish..
vacuum leak or 02 sensor
The pancreas, it releases insulin.
Check you APV valves.. They can get gummed up and cause poor performance.
because the need it to go for a run. other words so they have energy and won,t feel slugish
If he is more slugish than normal and not eating any thing also check to see if he has any outer symptoms of other dieseases
Yes, The vacuum advance advances the timing to help on acceleration and also will increase gas mileage.
if the fuel FILTER is cloged then the car either wont start if it is real bad or before that it will be real slugish especially going up hills.
Have you checked the ignision timing. Check the firing order as well
you will have a knock sensor code and the car will run slugish. when a knock sesor code is set its retards the timing so the engine will not detonate. the easyiest way to fix it is relocating the sensor.
some sympons of a fault tps is tht it bogs out when throtel is opened quickly alot of the time it will only rev up to a sertant pint like it has a rev limeter on it other times it may be very slugish at the begining then all of a sudded it just gets the power back after the throtel is opened about 30% to 50% i hope this helps you out "addtional info" to see if the problem is the tps disconnect the sensor. If you have the same idle your sensor has gone or is going bad.
