Also once it’s missing it misses regardless of gear, it only misses in the throttle if I ever so slightly push it but if it’s at any significant rpm it doesn’t seem to be missing.

I haven’t tried gunning it in park when it’s not missing as bad to see if that causes it(unfortunately it started missing bad again yesterday). What I mean by it missing after driving agressivly is that it doesn’t miss when in the throttle it starts missing at idle speeds after driving...

Problem always starts after I get in the throttle aggressively to pass ect... Yes I’ve pulled the valve cover and everything looks like they are functioning properly and all have the same range of movement that I can tell. New internals were basically everything besides the cam and crankshaft

Compression is still all the same 135-140(lower numbers may be due to rubber type of tester)I don’t think carbon would be the problem since all the engine internals only have about 7k on them and I’ve run some Seafoam in it but I’ll try another clean with the ol’ water trick. I’m going to test...

I’m not sure if it helps any but I noticed it misses a lot worst at startup then when the idle settles down it’s not as bad but still noticeable.

So the weak spark seems to have been fixed by the new coil(cleaned spark plugs as well to check go fouling). I have checked all injectors and they are in good working order I’ve even swapped them around ect. I checked out the cps cleaned the connection and what not with no change it is a newer...

I’m going to re check compression and try to re index the distributor, at this point it has to be something timing related. I’ve replaced everything and checked everything else that I can come up with. The miss went away (may have just gotten less noticeable) for a few days last week and came...

So I changed the coil to msd, and the fuel filter with no change I’m at a loos for what to do next nothing has made any difference that I can tell pulling the wire or injector on cyl makes little to no difference and it is definitely getting fuel and spark

I’m using the plugs everyone recommends I think it’s champion? Dist cap is brand new and no problems that I can find I’ve checked just about every electrical connection I can find and yes the distributor is properly indexed. all of the stuff that was replaced was in attempt to fix the...

Fuel injector is brand new and is definitely functioning. I have switched injectors with others (no change)and had a spare and ended up leaving the new one in. Cyl 1 compression is good (135 psi). The cat was falling apart inside and was replaced. Head was rebuilt just because of gasket leaks on...

Forgot to mention 4.0l Aw4 Np231

So I’ve recently been having some issues with my 96 xj it all started after I accelerated quickly to pass someone. What happens is that it misfires on cylinder 1 at idle and runs just fine at any other rpm with no power loss. This occurs at any engine temp. Engine codes are p0300,p0301. The...
