Thank you all for your help. I changed the plugs to autolite (not sure if it was the Bosch Plugs or the fact that several plugs were loose). I did not change the O2 sensor that sensor near the firewall doesnít look easy to change so i didnít mess with it. I will follow-up in a week but hopefully the issue is resolved.
On a side note what is the easiest way of tackling the O2 senor near the firewall?
Also I changed the IM upper and lower even though they only had 30K miles on them but they did have some oil build up. What is oil buildup on the upper and lower manifold gaskets indicative of?
When changing my Gen-2 O2
sensors, I made use of Advance Auto's "Loan-A-Tool" for a refundable deposit program, to check out their O2
sensor socket wrench set. It had a short offset socket that made all the difference in getting to & making the removal of the firewall O2
sensor a breeze from below.
