[stoner1993able]

i have a misfire in the fourth cylinder in my 98 k1500 ext cab chevy 350 5.7 180k miles i have changed the plugs wires cap looking to solve the problems it vibrates alot at idle and if i have lights on for a very very short time hard to start any ideas on what could be the problem? i think it could be the spider injector but not sure .... also some liquid coming from the exhaust with white smoke

[scottykilmer]

@stoner1993able often spider injector assemblies, that plastic crap stinks. But, first, do my video test "how to find out if you head gasket is blown" cause white smoke can be that, the test will tell for sure.

Scotty; What kind of experience do you have with the 3.2 yamaha engine in the ford taurus, I am looking to possibly buy a 93 with 100,000 miles. The engine has been recently tuned to get rid of a miss on the #4 cylinder, plugs and wires, which is not firing at all. I'm thinking of taking a chance on buying it thinking it's the fuel injector. Is it very probable that is is something more complicated such as internal problems?

[scottykilmer]

@MegaFlaxman DO not buy it, those engines are throw away. Lots of horsepower, but they fall apart with age and cost a ton to repair.

Save money...extra long screwdriver, put to injector, put to ear, listen to clicks.

@B2sick Man, if you're going to comment, at least spell manson correctly. And try a little harder next time, I assume you don't make a living doing jokes.

You might want to add when replacing fuel injectors that you need to clean the area around the fuel rail before taking it out so not to get dirt in the intake. Also when installing you need to put a small amount of lithium grease on the NEW o-rings of the injectors so they tear and cause leaks. I am a mechanic and this is a good video but leaves a lot of important information out. Sorry

@DonutMan181 watch my video "how to fix a car that idles poorly"

[DonutMan181]

@scottykilmer just out of curiosity, do you have a video of doing a job like that? just so I can get an idea of what it is I'm getting into?

[scottykilmer]

@DonutMan181 no super easy, but doable, it's on the throttle assembly.
