spark plugs

    Hi, this is my first post on this website, just so you know. I own a 96 Mustang V6 auto with 207,000 miles. For 8 months, my check engine light has been going on and off. The first few times it was a "cylinder 2 to misfire" error. So I replaced the spark plugs. Then a "cylinder 4 to misfire"...

    Hows it going everyone, I have been going to the parts stores a lot lately and been getting the wrong parts for my Stang. Its a 1970 Coupe with the original engine and drivetrain, 302, 2 barrel Autolite, c4. It does have electronic ignition. I have been running into this spark plug problem. The...

    I have a 1966 Mustang Coupe with a 289. Back in the day when I had a straight six it was no issue changing the spark plugs. Now I have a 289 with headers and a dress kit. Is there any way to change the spark plugs with out removing everything. There just isnt enough space to squeeze between with...

    I recently replaced the spark plugs, and spark plug wires on my 98 GT due to the engine misfiring. I wasn't too worried as my Mustang has 138,000 miles on it and I figured the original spark plugs or spark plug wires had finally failed. However, after using my timing light its clear that...

    I have a 4.6 GT Mustang and I changed the spark plugs, wires, and just today put it in a new Camshaft position sensor. The reason I did all that is because when I accelerate the car hesitates and keeps shaking through all the gears and at any RPM like if it had no power. It doesnt shut off on...

    I have a 2007 gt with CAI, long tube headers, no cats, 4.10 gears and for one it was running lean. For now until I get it back on the dyno i added more full with the SCT X3 just to be safe. I pulled some of the plugs and they are burning hot or white, which indicates lean to me. I want to...

    I recently installed a set of long tube headers and off road X pipe, and now I think the engine is running lean with pinging. I backed off the timing to ~10, but didn't help. I used starter fluid and sprayed around looking for a vacuum leak, nada Do I NEED a custom tune ??? And will it help...

    Ok, so I decided to start working on cars and i found a 1992 Ford Mustang LX hatchback for $300. The guy i bought it from said that it was a 2.3 inline 4cyl and told me i could look into a 5.0L upgrade kit, but i wasn't all that interested. Well, it's been stalling and so I decided to switch the...

    Whats up yall? It has come time for me to replace my Plugs and Wires, and as per my usual mechanic's recommendation (he is a bmw guy), I bought MSD superconductors, and NGK Iridium IX spark plugs. When I talked to the local Meineke guy (an F-ing criminal), he told me there was no way my mustang...

    Hey, I have a 2000 3.8L and I'm wondering performance wise, what you guys think is the best spark plug. Thanks!

    Just a quick question about the 302. I was working on my 302 yesterday, and noticed the spark plugs angle outwards. I noticed this before a few years ago when I got my baby but it never phased me until now. Does anyone know if this is just a trait that every 302 shares? or do I have High...

    Hello everyone, I just bought a 2000 mustang V6 3.8L a little of a month ago, i havent had any real problems with it until now, for some reason when i got in the car today, it felt different when i was driving, it feels like the car has lost some horse power, the car takes longer to get up. It...

    Hey guys... I know this has probably been posted somewhere but I figure why not ask here. Repair shops want like $100+ to replace spark plugs... Knowing me, I'd rather learn how to do it myself than pay someone else that kind of money. So if anyone can write down some easy to follow but detailed...

    I have a 2002 mustang GT convertible with only 42K miles, while driving about 20mph, I heard a loud bang and then a loud thumping sound while the engine was running. I discovered that one of the spark plugs (#8 plug) was completely blown from the engine - no threads left in the head! I have an...

    This 1985 has been apart for 7 years, but now everything is back together and should work.. Well it isn't. The car will not start. When we turn over or crank the engine, no spark is coming. My dad took a spark plug and tested to see if there was a spark at all..None. We have replaced the TFI...
