So I figure, maybe the one I got has a clogged filter, so I rig up rube goldberg fuel pressure gauge I can watch while driving,ĥ2 PSI all the time, even at full throttle pulls when the MIL flashes the misfire blues.

This one has an in-tank filter instead of the nice easy to replace one of the pre '05 models, so it was cheaper to get a junkyard pull full pump assembly instead of the fuel filter itself, so I got a pull from a car with 78k miles and install it, So at this time I'm figuring that the ignition system is completely replaced (with the exception of the main ECU), I turn to fuel.Ĭlean out MAF (non-chlorinated brake cleaner + compressed air)
So I tried a new set of plugs (NGK iridiums) Didn't really feel the misfire however, it is very faint and only noticable under full throttle, light throttle to redline and you can't feel it, sometimes the mil will flash on part throttle pulls, but will ALWAYS on full throttle pulls.then the light goes out, only comes back if I push it over 4000 and over 1/2 throttle, enough of these will result in it staying on and getting the flashing cruise control (perm codes set)įigure well the coil is probably ancient, I just changed the wires, with the HG job, so lets replace the coil. Shortly after getting it back together it got a flashing MIL on hard acceleration (misfire codes on cyls 1 and 2 (P0301, P0302)). Reset valve clearance to stock (was slightly loose by a few thou on most valves) Noted oil on plug wires, replaced valve cover gaskets and got cheap auto-parts store wires* (we'll come back to this shortly), installed new NGK iridium plugs.

Pulled motor this fall, resurfaced both block and head with the manual block-sanding method, installed new gaskets, torqued as per specification, reinstalled motor. Noticed it had a significant oil leak from both heads (head gaskets, external oil leak) I bought it in January 2016 with 203,000 on it (All highway, original owner, full maint log, good shape, ran great).
