Hi Im David, thanks for visiting the site. do you have a check engine light on?

Customer: replied 1 year ago.
but its been on for a long time before this started.
Customer: replied 1 year ago.
I have been told that a clog in the catalytic converter can cause this to happen on saturns.
Expert:  david craig replied 1 year ago.

well just because its been on for a while doesnt mean more fault codes arent being stored. you need to have it scanned for codes.

Expert:  david craig replied 1 year ago.

as far as being told its clogged catalytic converters that doesnt mean a thing unless you know they are clogged. that would require a back pressure test to be done.

Expert:  david craig replied 1 year ago.

i base my suggestions and recommendations on tests, not hearsay... throwing parts at a car because you think something is bad ends up costing you money and getting no results

Expert:  david craig replied 1 year ago.

so my suggestion to you is to have the computer scanned for codes. then we can find out what exactly is going on with your vehicle and take the proper steps to address the situation.

Expert:  david craig replied 1 year ago.

do you have a scan tool and a back pressure gauge?

Customer: replied 1 year ago.
in your professional opinion what could cause acceleration problem with a saturn vue?
Customer: replied 1 year ago.
no I don't have a gauge
Expert:  david craig replied 1 year ago.

it can be a number of thing. throttle position sensor. clogged egr valve. clogged catalytic converters, bad accelerator pedal position sensor. a bad computer, bad colipacks, spark plugs, throttlebody, clogged fuel filter, a weak fuel pump

This has been the worst help site I've ever encountered.
Expert:  david craig replied 1 year ago.

you are asking me a question that is impossible to answer. i have no idea whats wrong with your vehicle. you need to have the computer scanned for codes.

Expert:  david craig replied 1 year ago.

do you even a have a mutli meter or a scan tool?

Expert:  david craig replied 1 year ago.

if you cant even run to autozone and have them scan your vehicle for codes then i can not help you. im not into guessing.

Expert:  david craig replied 1 year ago.

ill opt out and let another tech guess
