what is the car? what are the mods? what are your symptons? have you pulled codes yet?
Not everyone knows everything about these cars. More heads are better than 1.

It would take me 8 hours to type out everything this car is doin it is a completly stock 95 gt with the smog pump removed have been fighting a spark knock problem since i bought it yes i know the ballancer spins i have checked it 50 times its fine but i put a new one on it anyway still does the same crap timing is all over the place when you can get it to start you have to anvance the hell out of it.... Set to 10-15 base timing shut it off wont start again not its to the point it wont run at all no matter where the dizzy is set coul if firing but getting no spark out of the dizzy whatsoever had 3 diffrent dizzy in it 2 diffrent modules cleaned and greased every connector checked every fuse still wot start and run

is the car red or blue?
Coil is fireing plugs look black as shit from all the fuel i was pourig in it without spark all day spout is out correct ho firing order it has codes 172 176 211 car is red and grounds are where i will go next with te old stock coil and base timing at 14 it spark knocks like a big dog and misses bad at wot im thinking that might be the plugs i will replace them tomarro but after all the bs the last two days my spark knock is still not fixed and now i have more problems ugh i think its time for either fox body efi a carb or 4.6 car what actually controlls timing the ecm or the tfi module

check the motor grounds below teh passenger footwell I hear people have been having them corrode now.
Yeah im goin to add an extra ground and power to the alt because i got a big sterio anyway deff wasnt 180 i the coul just didnt have enough spark to make it threw the cap and to the plug i put another older msd coil on it and set base timing to like 9 or 10 it dont spark knock anymore but misses very badly over 4000rpm im just wondering if all the spark issues and arcing hasnt taken out somthing in the ignition system but i think its at least drivable now i hope anyway i hope the plugs tomarro take care of the high rpm miss.... What do you recomend gapping the plugs? .055 ish?
Sorry i forgot to put that the coil was bad brand new msd not a month old put an old one on and fired rite up Deff wasnt 180 out im no genious by any means but i am a master tech and certified mercury marine mechanic i just cant get a grasp on this eec shit for some reason i know a coil any old idiot should be able to figure out but it was throwing a spark across a 3/8 gap that should be plenty to fire the plugs but i guess not... But the long and short of it is i spent all this time and agrivation this weekend trying to get rid of this spark knock problem and still got a bandaide on it running 9* of timing i thinkin about runnig 24# injectors with a stock meter and see if making it stupid fat helps with the spark knock i am going to get rid of the spark knock i also have a set of small body 4 hole injectors that look like ev6 ones but have ev1 plugs on em.... I might put in tomarro

your air and water temp sensors are also factor to the computer for fuel needs.
0.054 is spec for the plugs. So it has a MSD box? And you're having ignition issues, start there. I think if you start swapping injectors, you'll just compound problems.
What exactly do you mean by spark knock? Never heard that term. Is it like detonation, or 'knocking'?

Both coolant temp sensors are new and the ait is new it was running a litle hot i put a new tstat in it this weekend cleaned out the rad and block replaced a few bad looking heater hoses runs a ton cooler now between the o and r before it ran between the a so i thought it could have been engine temp doing it but it didnt help a bit other than it running cooler and l and no theres no msd box just a coil the one product that i still had faith in that msd sells fails on me in less than a month i already would not use their boxes distributors and wires they are completly junk but i still had faith in there coils and mags! But not no more im selling my pro mag out of my boat and buying a mallory lol.... The reason for wanting to swap injectors is to fatten it up and see if it is a lean knock and yes spark knock = detonation put about 25* base timing in your car and stop on it you will know what im talking about

Mine had a high rpm miss fire and I replaced the coil with a 42,000 volt summit coil. No more prob.
the tach signal comes from the dizzy.
What kind of dizzy cap do you have?

Msd cap and it gas a msd coul on it that came off a car that ran perfect also swapped out the tfi module with one off another fine running 95 auto gt i think im gonna try a dizzy and if that dont work im sending it to ford to fix.... Could o2 sensors cause this kind of problem? I have those two lean codes that have been on the car since i got it but it has had a spark knock problem since i got it also so idk
Don't change the injectors. Fouled plugs would seem to indicate too much fuel already. Also, the PCM is adding fuel based in the MAF signal as well. Have you cleaned the MAF with MAF cleaner? Needs to be done if it has been a while. O2 sensors have a finite live and by about 60k miles they generally start to fail. Did you clear the old codes? You want/need to know what is currently being logged by the PCM. Check the ground from the battery to the engine and engine to chassis. They need to be absolutely solid for the engine sensors to function properly. The PCM controls the timing not the TFI. Timing is mapped based on load and rpm.
well the plugs were fouled cause of all the cranking and no start they always looked great if not a little lean before. of the three codes in it the pip code was the only one that is out of the normal the two lean codes come back and stay after being cleared. the pip code is only cause i had a distributor in it that i know was bad after putting it in..... the maf was just replaced with a diffrent one off a 95 car that my cousin scrapped and i also cleaned it before installing i bought my car with a bad maf and got the car cheap cause it ran like shit and i knew rite off that it needed one i am gonig to add a #4 ground and power directly to the battery tomarro night and also check the ecm ground... where is the ecm ground actually located on the 95 cars i know the fox bodys it was on a rear intake bolt... im just wondering if the the o2's could be casusing a lean condition and thats where my detonation is coming from? i will do the grounds then switch out the ecm with the one out of the other 95 my cousin has if that dont fix it i will put a dizzy in it then o2's i guess and if that dont fix it hell idk i guess carborator here i come! and that sucks cause i really wanted to use the brand new tubular i got

I would do O2's before dizzy. The motor runs, it just pings like mad. that rules out the dizzy.
Make sure after you replaced all those components you disconnect the battery for about 10 minutes. Otherwise the computer will be using the old info that was stored from before.
