Also input on using an "engine clean product"? Or fuel system cleaners ?

Problem only occur when cold. Took idle speed control out and cleaned. Took ECU fuse out and disconnect battery cable also to reset ECU without any result. Once car is driven for awhile rough idle goes away. Once operating temperature is reached it still takes awhile for idle to Smooth out. What could be problem? It's evident that something isn't getting the right information to kick in and work on cold engine, to smooth it out. The power is there, does not stable, and runs well. Just idle like shot when cold. Has 234.000miles.

All 3 of my other windows roll up except for my driver side window doesn't roll up what could be the problem?

When my speedometer isn't working my dash shows a tranny error message my abs and srs lights come on but when the speedometer does work the dash is clear. Sometimes it will come on while im driving but the gauge just jumps back n forth from minimum to max speed.

The heater comes on and blows cold air but that's it. The dials all work hi and low etc but the air doesn't get warm.

We're do I find piston 1

It started with just when I started the car but know it's doing the noise also while I am driving

Everytime I open my trunk water falls and now sometimes my back seat gets wet

While driving up a steep mountain grade my flex plate failed, center broke out @ main crank bolts. Engine RPM's redlined and loud backfire (pop), and shut down. I replaced flex plate and then starter sounded like it was spinning. So i replaced with new one, with same result. Engine will crank and run momentarily, but then back fires and sputters out. What else might have been damaged to cause results I've described?

Replaces oxygen sensor and tps and it still does it. Has anyone else had this problem, whats the fix?
