Check fuel pressure, and exhaust back pressure, Exhaust backpressure high would indicate restricted flow... probably restricted converter.

    i changed my spark plugs and my valve cover gaskets and when everything went back together it wouldnt go pass 3,ooo rpm....can it be caused if i torked down the fuel injectors too tight?

    That doesn't sound likely, not even sure it's possible.Did you forget to hook anything up after the plugs and valve cover gaskets? Maybe something throttle related? do you have a check engine light on?

My 2003 cadillac cts automatic transmission will not change gears pulls off slowly but will reach high speed


please do not have your transmission flushed , have someone take the oil pan off and replace the filter as well and what ever trans oil you take out replace it as well . no automotive repair shop will warrenty your trans if it should suddenly stop working , but just for your satisfaction ask the transmission repair shop who flushs trans if they guarantee it and have them put it in writing . ive never understood why flush dirty oil and leave the dirty filter in the trans , it collected all dirt and metal wear which is what is causing it to plug up causing it to restrict the oil flow

I have an cadillac Cts 2003 with starting problems


the plugs are the problem, they become unable to ignite all the fuel when in idle, so that they get wet and won't give any spark until dry. try to replace them. if there's no difference the problem is at the admission system(fuel pump maybe)

Burning rubber smell inside car-2003 CTS Cadillac


Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL
