I've been on a journey. Said journey is not yet finished.

Replaced the fuel injectors about a week ago. I'm not very car savvy, so it was interesting for me to do. Now, upon immediate fire up, car idled BEAUTIFULLY. Straight phenomenal status.

Then the check engine light came on and it ran like garbage after heating up. Learned that the MAF Sensor's ground was disconnected, not getting power. Fixed. Then the PCV Valve wasn't seated right. Fixed, ran amazingly that night when I took it for a test drive. Next day I start it up and it runs like garbage again. Moreso when it's cold, less when it's warm. Had a cut vacuum line from somewhere coming out of the smog pump. Fixed, still runs like garbage. OBD1 tests returned 8, 41, 91. Oxygen sensors are getting replaced tomorrow.

The 8 part bothers me. If the Oxygen sensors don't fix the problem... am I taking my intake back off to reinspect the fuel injectors? Before reinstalling the upper intake manifold I turned the key on but didn't start the car, to see if there were any gas leaks. There were not...

I'm trying to get it fixed before I take it to a shop next Wednesday.

 

is the o/2 sensor gound hooked up??? I'd check that first

 

O2 sensor ground.... I was just thinking about that before I checked my mail. I was also thinking, where does the O2 sensor ground?

 

Drivers side rear bolt on the lower intake manifold?
