last night my car took a **** and turned out to be the fuel pump I swapped it out this morning cuz I still had it warrantied. Start the car and bam fires like normal first try everytime. I started to drive it around make sure everything was good, I role to my first stop when I start letting the clutch in a bit and pressing the gas it bogs really low about 200rpm and craps. turn the key and fires first try and works fine. what could it be.
