    Voltage drop and miss in vtec

    ok so update. (life gets so busy!) I might be repeating myself so I apologize if I do. I still have the stumble. I did figure out the voltage issue. 1. I forgot its a FIAT! electrical sucks. dont ask why but all switched power goes directly through the ignition switch, not a relay. it is...

    Voltage drop and miss in vtec

    interesting, the other thread pointed out Battery. I did even think of that. because I the battery is probably past the point where it should probably be changed anyway, I might just go with that first. it is end of season and the car is going into storage insurance soon. as well as I dont...

    Voltage drop and miss in vtec

    Cant see how it can be much smaller. Also why would it go down at higher rpms then? Might have to do a quick little drive to get a log. I am also thinking it is possible that the alt mighht be at fault even though its "new". Got a total miss match when i google on what to use. And i cant locate...

    Voltage drop and miss in vtec

    interesting thought. I didnt think of it until now, but, there was a pully change. albeit it would spin the alt faster. the original crank pully was chipped when I got the engine. I bought a new old stock one off of ebay. it was a bit larger but because of how hack the rest of the engine/car...

    Voltage drop and miss in vtec

    update, not good. googled and seems like the common answer is I should have 14v and I have 12.2v that drops to about 10v at higher then 5k RPM. I replaced the alternator once but am now seeing that I should have went with OEM. I am having issues finding an OEM alt. I am really perplexed on why...

    Voltage drop and miss in vtec

    Cake. The second one ran about 1 gal a min. The syphon happens on the push which was nice. I expected to pull up to pull the fuel. Odie

    Voltage drop and miss in vtec

    Picked up the second one. Will let you know how much my arm hurts after. Tank came in yesterday. Car is up on jack stands (yes i checked and they are not on hf recall :) ) should be starting the process tonight Odie

    Voltage drop and miss in vtec

    good thought! because I will be relocating the fuel pump I will check. The real crappy part about this is changing the gas tank, because of course you never have to change a tank unless it is full. and yup, mine is full. Fiat made this extra tricky as it is more vertical than horizontal so...

    Voltage drop and miss in vtec

    Screen, cap, rotor, plugs, plug wires timing, were all done last year. ( about 200 miles) but will check the screen as it is an easy check. Odie

    Voltage drop and miss in vtec

    Stock b16a with a hondata ecu. Warbro 255 pump. Misses when in vtec. Turn vtec up high enough to not engage and runs up to 7k no miss. Had this issue before and adjusted dead times to fix. Log shows running lean and voltage drops to about 10 amp when on vtec. Right now leaning towards toasted...

    Intermittemt miss under load

    Figured it out. Or at least got closer. Started looking at other peoples datalogs from the hondata forums. Looks like there are people whos voltage drops lower than mine. So my next thought was injector dead times. I know they vary with voltage as there is a table in hondata for it. Well my...

    Intermittemt miss under load

    still have not gotten to the valves. I did add a few grounds, and larger gauge wires to the fuel pump. sounds a little better but still misses. around 18-19 seconds you can here the miss with vtec. Also looking at the datalog. the voltage drops during high RPM. i.e log shows 10.98 @ 7600...

    Intermittemt miss under load

    going to do the valves as soon as I get a chance. good part is I will go ahead and do the retorque of the head bolts. I know there has been debate if if it is needed (arp says yes, many people say they never have had to) but if I am going to be in there already, why not. still in the debate...

    Intermittemt miss under load

    interesting thought. looking back I think someone recommended valve adjustment last year I even bought one of the tools to make it easier. I think it was supposed to be a winter project last year. I think part of the reason was I did a head gasket which of course requires removing the cams...
