1995 Dodge Intrepid 6 cyl Front Wheel Drive Automatic

We recently bought a 95 Dodge Intrepid for my son and it ran like a dream. Then the check engine light came on and we stopped and notice the radiator had a crack in it. We took it in to get it changed. We forgot to give them the key fob to turn off the car alarm and they accidentally set it off. They disconnected the battery to shut it off. Ever since we got the car back has ran terrible. It just started running rough at startup. If he turned it off and restarted it, sometimes it seems to run smooth again. Now it just runs terrible and has no power. Said it wouldn't go over 45mph. We took it back in and they changed the O2 sensor, crank shaft sensor, Cam shaft sensor, checked the coil, plugs, and fuel pressure. He said the fuel pressure was a little high. Can anyone help us? The next thing he wants to change is the module and that is around $300. Are we overlooking something? Here are the specs on the car: 1995 Dodge Intrepid, 3.5 V6, R16 tires.
Thanks for your help!

Hello, can you check for codes? If you think it might be a spark issue, I use a digital multimeter as a basic test, touching the plug wires one at a time, engine running. It is an inductive reading, you don't take the plug wire loose and you don't penetrate the insulation, you just touch the meter lead to the wire. I look for the readings to be close on each plug wire. If most of the readings are close and maybe two plug wires that show almost zero, I know where to start. I'm not saying that is a conclusive test, but, as a basic first test, it works for me and you don't have to unplug anything. I just wanted to add, don't let any meter leads get wrapped-up in belt or fan, anything.

I just stopped by and talk to mechanic. He listed for me what he checked and changed. Changed 02 sensor, crank sensor, cam sensor, coil and plug wires. Checked compression, fuel pressure, injector ohms, injector spray pattern (all good). Mechanic is great. Hasn't charged us a cent cause it isn't fixed. The thing that throws us is that the car isn't give any codes at all. Just runs like crap and then sometimes when it warms up. Runs fine. Ran fine for about 2 miles. Shut car off. Turned back on and ran like crap again. Barely got it home. Thanks again for your time

I have heard of a bad flywheel causing a sync problem between the cam and crank sensors? Just something to check.
