S70 Surging during acceleration
New to forums but wanted ask if anyone knows my problem with my car. I have a 1999 Volvo S70 base model and every time i accelerate it looses all power and dosnt go or it surges then dosnt want to go any faster when I hit the accelerator. I have checked all vacuum lines the MAF sensor is working the throttle is working. I also took it to the vovlo dealership and they couldnt find anything wrong with it after hooking it up and test drove it twice once i got in it a few hours later it started doing the problem. The check engine light isnt showing any faults going on and i hear nothing abnormal coming from the engine usually the check engine light tells you whats wrong to a degree but it dosnt seem to think anything is wrong. Any help would be appricated thank you for reading the post.

I havnt installed a fuel pump relay yet I did install a new fuel pump ill defenitly look into the relay and see whats going on with it. Dosnt seem to be running out of gas and it happens intermittently like if i get onto the highway or just try and floor it then it starts surging but if i dont floor it and ease into it it seems to not have the issue.
