when was it's last complete tune up?
'96 GT stumbles/hesitates when going over bumps
My car has recently started hesitating when going over large bumps in the road. It's really odd. The car will be driving fine and then ill hit a bump and ill watch the rpms drop from 1500 to almost 0, the car will jerk, and then bounce back to normal. I also noticed lately the car stalls at idle occasionally idk if that's related. Any help
Is appreciated thanks.

At 100K. Along with that since then I've put over $3000 into the car ranging from IAC To TPS to PCM to intake manifold, front end work, water pump, etc. it's never ending. I'm really hoping this is a simple cheap fix.
It would make sense that it's a loose wire or set of wires somewhere if every time you hit a bump it cuts out. There are obviously many wires in the car so it's difficult to speculate which ones specifically that it might be, but I would look into ignition related stuff and also since you mentioned something about replacing the pcm check all of the various points that it grounds at.
Ok yeah that sounds likely I was just talking to my friend and we agreed the same thing it could be electrical but would be very difficult to trace ugh.
Alright well here's an update: the car is now dead. I didn't have a chance to look into it before it died but obviously the problem has gotten worse. It stalled at a stoplight last night and won't start. Popped the hood looked around and noticed one of the ignition wires on the coil pack looked like it wasn't on all the way so I pulled it off and it looked black inside. Pulled the other three and they looked good. Figured this was it only to find out after replacing the wire and coil pack it still won't start she only cranks. Was that a different issue or a fluke? I'm totally lost.
If you replaced the coil pack and questionable wire, it seems reasonable to believe that it wasn't the issue or at least not the main issue.
Exactly my point only now I'm totally lost it won't start so no codes no nothing.If you replaced the coil pack and questionable wire, it seems reasonable to believe that it wasn't the issue or at least not the main issue.
Hey everyone, I know this is from a while ago but I figured since the problem just recently got solved that I'd follow up in case anyone has a similar issue. I had to bite the bullet and bring it to the dealership. No local garage nor myself could figure this out and I'm pretty decent I'd say with cars. 3 trips back and forth to Ford diagnosing and "fixing" only to find the problem back again and then back over the course of months resulted in the entire problem being a bad ground wire near the rear of the intake manifold. Absolute nightmare.
