HOT PLUGS FOR A 3.1 bUCK cENTURY - Cars & Trucks

I am assuming you have a 3.1 v6 engine the spark plugs are 3 right in the front next to the oil dipstick and above the exhaust manifold you can follow the wires from the coil to find each plug. The other 3 are on the back side of the engine and can be difficult to get to. Easiest way is to remove the upper engine mounts and tilt the engine forward a few inches with a ratchet strap or something to gain clearance. MAKE SURE it is secure because your arms will be back there. And those three plugs are in the same location as others just on the opposite side of the engine.again just follow spark plug wires down to the plug.

Quality wires, iridium plugs and air filter , close to $100 for parts. You doing it yourself will save a lot on labor . 3800 V6 ?

it sounds like vapor lock in the gas lines or might need to replace spark plugs but if it happens only when its hot vapor lock sounds right .

Can you check cylinder compression? Hope you didn't get it too hot?

Have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, check fuel pressure and injector pulse. Can you check applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.

this happened to us on vacation. Catalytic coverter was plugged. It did this for a long time before overheating on a road trip. Have someone reputable check it, if it is hesitating a lot.

its tough, thats why mechanics make the big bucks. there's no easy way. One way that will help is if you take the 2 front straps off the radiator support (torque straps) and fashion a way to pull the engine forward, tilting it towards the front.

Could be the crank sensor or ignition module. Does it happen more when the car is hot, or all the time ? These seem to fail more when the car is hot. Good luck!

i had a 94 buick lesabre and due to the the crank sensor i had a misfire
