i have a sylender or two that are going bad, i am going to do a compression test tomorrow, but i know that i am about to have to get new internals and possibly have to bore the cylenders. anyone have suggestions on what kind of internals i should get? its a stock f150 block with 9:1 compression...

at an idle and at stoplights, smoke comes from the engine oil filler breather, and it has a slight miss. also, at medium and high speeds, when letting off of the throttle, the air/fuel leans out completely and the engine boggs down a little causing the truck to slow down a little. i dont notice...

my truck is showing all the symptoms of a bad MAP, smoke coming from the valve covers, sputtering, "missing" long crank times when starting. i would think its not ok to drive like this, but is it ok to atleast drive a few miles for parts? and has anyone had any problems with their MAP? ive never...

I live in Norman Oklahoma and i dont really know of any good tuners around here. i know i could just look one up very easily, but if i can find one that is credible with other lightning/cobra owners that would be awesome. any help would be great! thanks guys:beer: -matt

ive been going through plugs a lot lately, in one cylinder in particular the plug has been melting pretty badly, enough to basicly melt the electrode all the way off or completely close the gap. i tried changing to NGK TR6 plugs, and i changed the injector on the plug melting cylender to another...

I decided to try the PCV delet. it seems to be running about the same, maybe smoother. i have been having some problems running lean, maybe this will help. it is still melting the #4 plug when i get on it heavy. i am going to switch that injector to another cylender and see if the problem...

every time i get into the gas WOT for any amount of time i tend to melt my #4 plug. i have been wondering if this is a problem with running lean on that cylinder because of a faulty injector or a vacuum leak. I have Moto blue HO coils and denso iridium spark plugs. does anyone have any ideas as...

im about to buy some new coils and spark plugs. im on the LFP website and i dont know what plaugs to go with, i tend to burn up plugs almost on a daily basis lol. i guess its because ive been running pretty lean lately, but ive almost got the lean problem all figured out

i have an oil seperator, but the rubber fitting are rotting and leaking, and i was thinking about going to a delete setup.. i was just wondering if anyone has done this and how it worked out for them

my aem AF ratio gage stays at about 15-16's to 1 ratio, then when i get into it the truck goes into the 10's and 11's like it should, but when i get up to 60-65 mph it goes lean and the motor cuts out pretty hard. other than that, from stoplight to stoplight it seems to run fine. I have changed...

so i have been having a lot of trouble with running lean. i changed all the o2 sensors, got a new MAF, got all new plugs. i guess the only thing to do at this point is start checking for vacuum leaks. has anyone else gone through this? and if so where is a common vacuum leak area? any...

i am burning up my spark plugs everytime i get fuel throttle for more than a few seconds. i have been trying to work this out for some time now, and i think that i have narrowed it down to it being too much fuel. i have 42lb injectors with stock eaton and pretty much completely stock setup. i am...
