I would also drian the oil , if its totally flooding because of way to much fuel and mixing with oil, kiss your cylinder walls goodbye. check the oil level to see if it is higher than normal. if it is , the its overfilled because its mixed with gas now!!!

I definantly plan to change the oil soon. Honestly, I do so about every month and 1/2 just becuase I'm trying to flush out the system nice and good. Also, I'm paranoid of this car sitting around for long times like it has been doing the past few years whenever something goes wrong.

At least fix the vac line that's supposed to be attatched to the other part that should be the regulator, which may also need to be replaced if the fuel pressure is wrong. I believe low vac at that line (as if you stomped on the throttle) raises the fuel pressure, which would definitely richen the mixture if there's no vac at the regulator diaphragm. You probably should borrow/buy a fuel pressure tester to find out exactly what's going on and to ensure that the needed repairs completely fix the problem. The fact that it runs like it does with the AFM unplugged also points to it running slobbering rich. It should practically die if that is unplugged. Check your vac lines, as more of those little rubber fittings may be deteriorated causing vacuum leaks.
Fuel Pressure Regulator - General Information and Replacement Otherwise, the motor sounds great from what I can hear in the vid. The fuel injectors do tick pretty loudly, so that is no cause for concern. If it still runs badly once the fuel system is fixed and running correct pressure, the AFM could be the cause as well as maybe the DME coolant temp sensor, but you won't be able to tell with the fuel system/vac lines in that condition.
Clark's Garage Home Page , "garage shop manual" on left navigation bar has lots of info that will help.
Take care of those things and let us know how it goes. |
So once I change the pissy FPD :P if that doesn't stop the problem, what else could it possibly be, ye think?
I've got my fingers crossed and prayers pronounced that it simply is the FPD causing this mess. Like, That day I drove it, it was completely fine, Started right up with no problem but just a few hours of sitting and not smoke everywhere and hard to start and keep on from a cold start. Up until this day which it will only stay on for 2 sec then die again. I tried unplugging the FPD and FPR then cranking the engine, it will turn over but still somehow (I'm assuming) floods out and dies.
Ugh, it's early, and my human DME (brian) isn't functioning well :P lol
