04 Prerunner vibrating and losing power

I have an 04 Tacoma Prerunner And today it started vibrating, feels like it loses power and after a few seconds the power releases.
What do y’all think it might be?
Thanks for the help in advance.

 

You gotta give us a little more description than that. When does it vibrate? Is the check engine light on? What do you mean the power releases?

 

When I hit the gas pedal it starts to vibrate and after 1-2 minutes is when it starts to accelerate.
I don’t know if making any sense.

 

Is the engine vibrating or is the whole truck vibrating?

Just a shot in the dark, when was the last time you changed your spark plugs? I'm leaning toward an engine misfire.

 

Just the engine.
I bought the truck 3 years ago and I have not change them since then,and I doubt the previous owner did.
You’re the 2nd person that have said the spark plugs. And they've said, it could be the gas pump?
1 week ago I took it to Toyota for an oil change, but they never told me it needed a new set of spark plugs.

 

They wouldn't know from an oil change. You can't rely on the dealer to tell you what needs to be done when you take it in for an oil change. They do a quick visual inspection and let you know if they see anything obvious, but they aren't going to go through the hassle of removing a spark plug. That's on you to keep track of when they need to be done. You're supposed to replace them every 30k miles. Sounds like that's where you should start.

If they've been worn for a while, they can over stress the coil, and you may wind up needing to replace one, if not all the coils.

Typically if you had a fuel pump issue, it would be a starting issue. Like it wont start occasionally, or it wont start at all, or it cranks for a while before starting.

 

Feel like that’s the problem.
Thank you for your time man, I really appreciate it.

 

Anytime bud. Hope I didn't come off like a dick or anything. It's frustrating being inside the auto industry and people expecting us to use our crystal balls to tell them what's going to fail in the future, you know? No it wouldn't be that hard to pull a plug and tell you that they need to be done, but every job (oil changes included) have a time limit, and if a lube tech does everything properly, there isn't much time leftover. And if they dont hit their numbers/quota, then they get called into the office for underperforming and it all goes downhill from there.

 

Thank you, i hate people who think i have to check everything when its only in for a tire leak. If it was a fuel pump problem there would likely be a code, maybe not the CEL on but its there. You can always pull codes or go to a auto part store and ask them to do it.

 

No worries man.
I was just surprise that it started to do that. I take good care of my vehicles. Specially my Tacoma. But every vehicle has its problems.
I’m changing the spark plugs tomorrow.
Thanks once again.

 

I'm not saying you dont. I'm glad to hear you appreciate your taco, they're awesome trucks. Here's my suggestion. Find your maintenance guide and look it over. Start knocking off things that probably need to be done. Like transmission service, axle and transfer case services, timing belt and water pump. These are all things that are going to improve the longevity of the truck.

 

Hey buddy,
I changed the spark plugs, and everything worked well.
But now when I turn they a/c on it starts to shake.
What do you think my problem is now?

 

The motor? the whole truck? Whats shaking? Does it increase when blower speed increases or only start and end when the ac button is on?

 

Shaking like before? Meaning a misfire? My guess at this point would be one of the coils is damaged and needs to be replaced. Are there any DTCs?

 

Just motor is what shakes when I accelerate.
- are you talking about the ignition coil?

 

Yes thats what he means, is the CEL on? If so check codes, actually regardless of if its on or not check codes, some codes dont turn the light on if they are pending

 

Yes an ignition coil. I'm betting one is bad.
