Having problems with your 1997 Buick LeSabre ?

Clogged fuel injectors

\015 When i drive for awhile my car jerks like i need spark plugs and wires but i have just gotten a full tune up what would make it do that?\015 Posted / edited by AnonymousUser on : 19-02-2018

Answers :

In the tune up was the "Idle Air Control valve" cleaned thoroughly? Many folks overlook this...also new air filter, and fuel filter? Sometimes a good fuel injector cleaner like "STP" super concentrated in the black bottle...try adding 2 bottles to your fuel tank, and go from there...should make a difference on your Buick 3800 OBTII...Hope this helps.
