OK so last weekend I changed out my injectors with some known good injectors. The old ones looked very bad and I was thinking that they were the cause of my running rich. I also went back to a colder plug (NGK) as I was worried about running the Bosch Plats figuring they were too hot.
Well it appears that did not fix the problem. I think I loaded up the plugs again (wife is bringing SP wrench and old plats to me at lunch time). Car was bucking and missing all over the place. Barely made it to work. All wires are connected injectors firing good spark to all cylinders etc. If I can't figure this out I am not going to risk a 200 + mile trip. Here is what I know is good or what I've done do far. MPS is good - holds vac rebuilt by Geoff. Cold start valve unhooked and bypassed Injectors changed to known good injectors. All vac hoses are brand new. Ignition is pertronix with a pertonix coil. Car starts up immediatley. Good fuel pressure - right at 29 lbs. Inline gauge never waivers. What am I missing... this thing is still puking black smoke occasionally and smells very rich. Where should I look now. (IMG:style_emoticons/default/confused24.gif) |

I've got carbs, so this is a stretch, but you seem to have covered averything in the FI system. Did you change the fuel filter? My car sorta suddenly began to run like crap after having been up on jack stands on the drivers side only. I decided to replace my less-than-a-year-old fuel filter last night and poured all kinds of RUST out!! Have you ever cleaned out your tank? I had not, but I will be soon. Suggestion- Check fuel filter before you replace those plugs again.
