Question Is it difficult to replace the throttle body on a 2003 chevy suburban
Answer Hi Ralph... No Not really....are you changing both upper and lower...most problems are because of problems with gaskets between the upper and lower intakes....a quick check is to run the truck and using air intake cleaner spray around the throttle body and intake and see if you have a rise of rpms when spraying..if you do you have a leak....change gaskets before changing throttle body...hope this helps
