Truck struggles to go past 3,000 rpm's and intermittent not shifting

Hi,

Did this problem just start since the plugs were replaced? If it got worse since you replaced them, see if there is a new code that indicates which cylinders are causing the issue. Also, make sure the grounds weren't damaged for the ignition coils. See pic 1 for locations. Check to see if the connector at the ground point isn't loose or damaged. I've seen many of them break. If one does, you will have 4 of the cylinders working.

Let me know. Also, reconfirm that all connectors are tight and properly attached at the coils. Anything is possible.

Let me know what you find or if you have other questions.

Take care,
Joe

Yea, I will let you know. It's in limp mode rn I'll check in the morning.

Hi,

Let me know what you find. Rescan and check the grounds I mentioned.

I look forward to hearing from you. Don't worry. We'll get it taken care of.

Joe

I checked the grounds they are good. So what could it be?

If the coils are all good and working properly and there is no issue with the grounds, we need to scan the computer to see what new codes are set. Make sure by accident nothing was left disconnected as far as sensors and or vacuum components.

If you have a scanner, let me know what codes are present.

Well, sadly it ended up in a broken head gasket.

Hi,

I'm sorry to hear that. Regardless, have you gotten it fixed?
