So got it finally running to what it should be. After replacing my fuel filter, new fuel pump, several sets of spark splug and a new set of plugs it actually turned out to be my timing being way off. Damn the simple things and over looking!

Well fixed one thing. Looks like the sensor that plugs in to the head had a bad connection, it now revs to whatever I throw at it. It still isn't 100%, still times when it will suddenly "open up" and power is all there. Going to check fuel filter this weekend, still running nasty rich as well.

Cool thanks will do that this weekend. Im also running scary rich. Outside of my car reeks of gas need to get that handled as well just not so sure how to adjust that.

Will have to take a look at that, fuel filter has not been replaced. If it was clogged though wouldn't I notice a problem with me fuel pressure? Guess I didn't mention it in this post, but it holds at 32-34 PSI, probably slightly higher the one I bought was leaking.

From left to right #6,5,4,3 Did not pull 2 or 1 yet.

Yeah I was thinking about doing that before even making the post. Think I will stop by the auto parts store and pick some up. I'm gapping at .040 is this the correct amount or am I too high?

So I have been having loss of power after 3500k rpm and it not really being able to break 4k rpm under load, my gas mileage is not doing to great either. I found that my #6 cylinder was not firing, replaced plug (was very dark and fouled most likely from problem with CSV that was been fixed as well) so thats correct now. Fuel pressure is holding at a steady 32-35PSI. I switched to dished pistons per furture turbo build from the flat tops (f54/p90acombo) so obviously I'm running a lower compression ratio. Ran car for a week and just pulled plugs to look at them. #6 still looks a little darker then it should be but 5-4-3-2-1 are looking lighter then they should be so I believe I'm running lean, is this correct? How do I tune my AFM correctly? Searched for it but I was hoping to find a more picture by picture instructions on how to do this.

Which one are you at? Im pretty basic when it comes to figuring this out. My fuel pressure is at about 32-34lb. #6 cylinder wasn't firing, replaced plug and wire and that solved that but it still has problems breaking 4k and power still doesn't feel quite right.

On start up***

My 79 started spitting oil out of the exhaust obln start up and initial idle. Does not do this when its warm. Not burning oil, no smoke so atleast I don't think. Any ideas?

Is there any way I can really check to see if the ignition module is going bad? Distributor seems pretty solid and no movement but I can check it out again. Trying to get my list ready for the weekend of things to check!

New plugs and wires, spark is strong. Injectors are good and fire corretly, timing is set 10 degrees advanced. Hoses are good, no known vacuume leak anywhere. It reves freely to 6.5k its just once in gear it hesitates.

Any ideas anyone?

Yeah I'm starting to think that it could be that, but im literally in the same spot as you. It feels strong, but its not what it should be. I'm starting to think it could be fuel delivery as well but injectors are firing just fine, fuel pressure seems to be good. Just don't know what it could be and its starting to irk me!

After rebuilding my l28e and having the car moved to Vegas it isn't as "peppy" as it once was. After 3500pm it almost just flat lines in power it seems, random bursts of power then flat line then repeat, it also has a problem breaking 5k rpm. Not that I'm going around racing all over the place, but it just doesn't as alive as it use to be. Could this be due to the 2,000+ feet in elevation difference and that my AFM needs to be tuned for proper air/fuel mixture? How do I do this? Should I just try to find an AFM out here that has been on a car that was built for the elevation here?

Thank you sir took about 2 minutes to find one after that

So everyone is special order on these, well pepboys seems to be the only one that can special order an injector clip. #3 one is just to corrodid. Anyone know where I could possibly get one by tomorrow? Not feeling all this misfiring =/

Recently rebuilt my 82 l28e with dished pistons new crank new rods/pistons/gaskets/seals stock intake and exhaust, put it in an 79 body and can not get it to run consistent. Had to swap out bad tank and fuel pump. Fuel pressure good, timing set at 20degrees, getting strong spark. It will run great for 2mins(900rpm idle) and then run like a dog. Changed fuel rail thought it may of gotten dirty, compression test results in120/130/135/135/130/130. Now I can't get it to even start with start fluid. Any ideas? Also have a p90a head on it but can not find the wiring to hook up the head sensor.

Agreed, guess I'm going to start reading it line for line tonight, hoping to have it towed in the garage this weekend! Thanks again! ...you gotta admit, you are a little bit jealous of my new dash

Yep, slightly read all of those actually. Guess I should of thought it out some more before I made the post, sorry! Over all, just aiming for something a little more then just a stock setup. Guess I was thinking silly questions for a minute!

Hey guys, first time making a post been trolling for a few weeks now. Was driving a 82zx N/A but ended up spinning the #6 bearing in my crankshaft. Tried my best to smooth it out, replaced it with a new bearing and spun that one 20 miles later. I just came by a deal for a 79zx in great condition. The head has been removed off the engine, but I'm getting a f54+p90 head out of the deal too. I was going to go the MS route and get a large turbo, etc etc. After research I have decided that the amount of work (and limited mechanical knowledge) I was just going to pick up a 280zx turbo ECU and harness and keep it basic. One of my questions is, is if I get a slightly larger turbo, to run around 12psi, would the ECU handle that? Would I have to install a IC? I figured I would pick up some slightly larger injectors (370cc, is that right?) versus going to the 440cc and running too rich. Would this work? I haven't been able to really find anything. Any help would be appreciated guys! New interior looks nice, not a crack on that dash!
