I've searched just read please

I'll give you the story of events that lead up to these problems and what I did to try and fix them. About a week ago I flew up to NY and stayed there for about 5 days so my car sat at my dads for that time. I get back and drive it about 30 miles home with no problems. I was on E so I went and filled my tank. The next day I start the car and it has an irratic idle. Going from 1k up to 2k and back. I figure it might go away if I take it for a drive. I get down the block and the car doesn't want to go anywhere. I give it gas and it just doesn't go. It sounds like its misfiring. It backfires and bogs. I figure it might be my D16 dizzy going that I have been running on my B16 so I finally use this as an excuse to swap it for my new B16 dizzy which I got in the mail a little while ago. I swap it and adj the timing but that didn't solve the problem much. I let the car run for a bit to warm up and then adjusted the idle speed and got a timing light and adjusted the timing. When the car is warmed up it idles right at 750 and drives ok enough to get me around, but it still has a loss of power when driving and it boggs for a second then kicks in and goes. thats the best way I can describe it. So I think it might be a bad tank of gas since I just filled up. I let the tank run down and refill the tank but that didn't do a thing. So I next replace the fuel filter and O2 sensors since I knew the sensors were bad and I am not sure the last time the filter was changed, That also didn't do anything. Next I think it might be the EACV since the bogging and loss of power are simptoms of a bad EACV. I take the old one off and cleaned it. That didn't change anything so I replaced it with 2 other EACV's and they both didn't change a thing. I am also getting about 18 MPG right now. I am now at a loss of ideas. I'm thinking it might be the fuel injectors but I can hear them clicking so I dought its them. Any help or ideas would be great.

possibly engine ground? Fouling spark plugs?

 

hmm sparkplugs I'll check those. I checked the grounds like 50x but it never hurts to try again. thanks any other ideas would be great.

jeez what's left?? uhm...TPS may cause those problems but i thought it would limit your rev range and you don't mention that. may want to bust out the old multimeter and test it at idle and WOT....i forget what the readings should be.

i'd take the intake arm off and check the throttle body for obstructions too

 

Yeah I took the intake pipe off and checked for suction and to see if anything was in there. Nothing was. I also followed the helms to check the fast idle valve and its working fine aswell. I pulled the tps aswell but it seems to be working fine. I pulled the plugs and they are white which indicates advanced timing, or lean fuel mixture. I am actually running the dizzy fully advanced because the car actually drives a little better with it this way. But the problem was there before I advanced the timing and the plugs are only about 5 months old. I also forgot to mention that the first few times I start the car it revs up and down a few times then stalls out. By the 3rd or 4th start the car idles up and down then after about 10 min it settles at 750 rpm. I also checked the vacuum lines for leaks but that turned up nothing. I'm going to buy some new plugs and wires in a bit to see if that does anything. I dont think the wires have been changed in a while aswell so we'll see. I think I have checked most of the common things so I'm asking all of you to help with the things I might not have though about. thanks. I bet its somthing real simple to.
