bucking and hesitation in 1999 SC400
My car has been bucking and hesitating mildly and its getting annoying. I am not sure what is causing it but the car for not have the Pp section for me to try the diagnostic port jumper to +b.
Also all this started when I stretched out the spring to better connect with my new sparkplugs (this was to correct a previous problem, which it seems to have).
So two questions:
1) Where can I buy the springs in the Ignitors on the 1999 SC4?
2) Why doesn't my car have any metal in the Pp section of the diagnostic port? What is the easiest way to try jumping the or eliminating the 9-12volt ecu switch?
