Hello and welcome to Just Answer

do you have any check engine or other fault lights on?

If you do then the next step should be to plug in a scan tool to extract the codes

as this will greatly help with the diagnosis

I'd also do a compression test across all cylinders to ensure that they are all within 10-15 psi of each other as this will show if the base engine is OK

Hi
do you still need help?
Bear in mind that the site takes a deposit from you at the beginning and this is held by the site until you rate my answer at which point the cash is split between the site and the expert. I am only paid for my work on this question if you rate my answer, using the star system at the top of the screen. Please do not forget! If you're not pleased, also let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent further replies
Thanks Matt
