Motor shaking and sputtering

So I just took a trip in my truck to luray VA truck ran perfect on the way there was coming back took a stop for about 30min can put started the truck motor was jumping an shaking so bad it was shaking the hole truck shook even worse in gear when I went to take off it sputters really bad for about 15 mins of truck but then clears up but if I stop for awhile then go to drive again it comes back. Anyone know maybe got back gas with water in it. Have no clue what it could be! I have a video I could share of it if anyone wanted to help an know further details thank you

 

That sounds like my truck when there are issues with the spark plugs or fuel injectors. Check engine light?

 

Yes check engine light but it was on before this happen for a evap system leak. I just changed spark plugs couple months ago put E3 spark plugs

 

Could be a vacuum leak - they tend to go away once the engine is warm like you mentioned. No way to say for sure without looking at it and running some tests. Ignition, air supply, or fuel problems could all cause that unfortunately.

 

Ugh that’s for all the help

 

So I got the code read it was cylinder 3 miss firing I changed the ignition coil 90$ later an it’s still doing it an just sitting here an can’t figure out what it is

 

My bet is a leaky fuel injector because you started the car while it was still warm then you started getting the problem. If it was a coil pack it would have been two cylinders I believe. I have the same exact problem right now

 

Depending on what motor you have, it could be oil leaking around the valve cover gasket and shorting out the spark plugs.

 

Mine did the same at 160K miles. Same code. Replaced fuel injectors and issue went away. 2000 PreRunner 2.7L

 

You can do a compression test on that bank of cylinders and find out if it's a mechanical cause for misfire in that cylinder if it's way below the other two. If it's not then it could be a plugged injector (or other things ) You can use the screw driver test for the injector to see if it's misfiring.

 

Compression, spark, and fuel. Test In that order

 

Pulling the spark plug for a visual inspection wouldn't be a bad idea since it's a 15 minute job since it's on the passenger side and he already replaced the wire. Then compression and fuel for sure.

 

So I replaced my number 6 injector, and now running smoothly. Its funny the code reader at O'Rileys was saying both #3 and #6 were misfiring, which stumped me. Because the misfire didn't move when I rotated my coil packs.

Did it in 3 hours

 

Thank you for the help because my code is reading the same exact thing!
