My car spits and stutters, feeling like it will stall when I lightly push on the accelerator. It doesn't happen when at neighborhood speeds only when I hit about 40 mph and up. But if I push down the accelerator the sputtering goes away. I have no problem idling, going slow, or cruising. I just had the manifold replaced, could that be causing this?

Hi jjszabo, Welcome to 2carpros and TY for the donation

Clean the MAF sensor with an electronic cleaner CRC and test the throttle position sensor-

I guess my issue is that this problem began after getting my manifold replaced. It seems too much of a coincidence, since I never had this problem before I dropped it off to be repaired. Then immediately after I pick it up this happens. Could the repair be causing this or maybe something was bumped, damaged when they were installing the new manifold?

Check the EGR valve and IMTV, also all wiring connectors within the intake manifold and vacuum hoses
