Re: Car back to running like sh!#
I did not make spyder hoses for secondaries that was the PCVs. I believe these coils were replaced at some point going to pull them and swap see if it goes away.

Re: Car back to running like sh!#
They all Ohm ok and no leaks when pressurized........did not check flow. I swapped pumps, maybe an issue with them? Any thoughts on checking primary pumps, where is the secondary pumps fuse?

Re: Car back to running like sh!#
Pulled the 2ndry fuse to check the primary pump........it gets up to only 40lbs.....and it flickers on its way up. This is one of the pumps I changed after the lean condition, and it was a used pump off my 21K mile 92.
I will swap today(I say that alot lately) and see if it makes a difference. Dammit!(Sorry just had to get that out)

Re: Car back to running like sh!#
By the way 2ndry fuse is easy to access contrary to other post, its two small bolts and then some velcro tabs to remove and then its right there and in reach by hand.

Re: Car back to running like sh!#
put in 1 new secondary as I was getting a lean code at high RPM......assumed it was the 2ndry, then it turned out to be the O2 sensor.
