Getting a lag or 1-2 sec hesitation out of my 2000 eldo etc as well as my 00 seville. On the seville I did a few wot's and it went away. On the eldo I just put a new fuel pump oem part and a full tank of super. Also filter is new also. When i mash the throttle I get a break up lag then spins the wheels and runs great. Any Ideas? Also I did not get gas from the same stations so i do not think that is a problem. Any ideas Guys i have 90K miles mabye time for a tune up. BTW air filter and oil are new also. Engine Idles so good you do not even feel it and runs great but the hesitation is bugging me. Thanks,

I will check codes today. The tranny shop just put some new CV joints in due to one breaking when these idiots were driving the car, Yeah I was pissed. But if they added tranny fluid it is possible they messed up the wires to the mass air flow sensor although they look fine.
