Default 1989 Bog on Acceleration/Low

Replaced the hood on my 89 and in the process, wonder if I knocked something loose. When I started it up afterward, was very hard to start, and when it finally fired, it would bog when I tried to give it gas. Replaced the fuel pump not long ago, and all injectors were replaced tow years ago. Don't drive much but took it out about three weeks ago and everything ran just fine. Took the headlights out when i replaced hood, and though you wouldn't think I knocked something off/loose during the change, I'm looking for anything to check that might be causing the hesitation. Runs pretty rough through first gear, but as speed picks up in second and third, engine seems to smooth out.

Ideas??

I'm having the same problem. I ran the codes and I got some that directed me to MAF sensor and TPS sensor. Check your codes. Maybe you knocked them sensors hard when changing the hood. Doesn't hurt to check
