98 SOHC Trouble Codes
|
Great insight here! Got upper and lower Intakes off to change out those leaking D-rings. Checked the IAC valve, seat looked clean. Question is... will this cure the cylinder (4,5,6) mis-fire code along with the lean burn code on 4,5 & 6? At 85K, she just started the Cold Idle RPM swing. Gas milage has been steadily dropping to 16mpg freeway. After seeing the deformed lower Manifold gaskets, I wonder about all the O2 sensor replacement advice I was getting locally. Thanks
