car running fine son got dui car was parked 3 months

It does not start moving according to my speed until about 10 to 15 minutes into driving. Recently had transmission done about 5 months ago and after sometime of regular driving it kicked back in but a week ago had to get a new alternator and now it has been 3 weeks and it is still delaying to work properly. My check engine light and TACT OFF light is also on and comes on after about 10 minutes later as well. What do I need to get fixed or done because I need to do an emissions test soon?

just had my transmission done and now the speed odometer and the tachometer are not working. Plus the sun roof is not opening as well.

must this be done at a Lexus dealer? Does the water pump need replacement as well? Anything else need work during this procedure?Which engine do I have. Will it be destroyed if belt breaks? Thanks.

The car and rpm goes up really high like some is stepping on the gas pedal.

my rpm needle goes from 2000 and drop to 1000 rpms up and down constancely and it travel about 45 mph w/out putting my foot on the gas.I have perchased a position throttle sensor and still have the same problem.

All the others work and I am wondering if this can be fixed or need to be replaced.

My car was running 3 weeks ago then I had to take it for some body work we have checked fuel and thats good but there is no fire to the coils

the pump has been replaced also the alternator. I need to look at a drawing of the system please.

my car will only go in gear if i push the shift lock override button. how do i disengage this?

brake lamps dont turn on

sometimes my clock changes, and when i use my blinker the radio cuts out for a second. sometimes when i hit the brake the radio cuts out for a second. can see dash lights slightly dim when i hit the brake. doesn't always do this.
