CADILLAC DEVILLE GAS PROBLEM

1993 Cadillac Deville • V8 Automatic •

This past weekend, I did some work on my 1993 Cadillac Deville. I changed the passenger strut/shock, changed the lines to my windshield wipers, self-bled my brakes, and most importantly changed the front and rear valve cover gaskets. I am proud to say that it was a success and there are no leaks (even though my brakes still feel weak), but all of a sudden a new problem arose. Now my car will barely move when I put it into 'DRIVE.' I have to put it into second or third gear in order to get it moving. So my questions is, what is the problem, what line or screw do I have to tighten in order to get my car moving normal again? It moves perfect in reverse, but soon as I put it in drive, its like an elderly person having to take a first step. I did do alot of climbing on the engine when having to change the rear valve cover gasket. I also will like to note that I do hear a slight whistling sound coming from on top of the engine.

Re check your work especially all the vacuum lines. It sounds like you may have a line off or broke,

did the check engine light come on?

How is the fluid in the trans?

Lol, ok I will admit, I did break two vacuum lines. They were plastic and I replaced them with rubber tubing. Is that ok? The check engine light didn't come on, but its normal for it to come on and off. When I had finished working on my car, I did tighten the nuts to my transmission pan and ended up destroying the gasket (fluid leaked out overnight). I just changed it today so I will see if all is well tomorrow (Tuesday, 8th). Do you know what vacuum line it could possibly be? Is it significant if the base of the throttle body doesnt have a gasket (I'm buying a new gasket)? I also saw that my speedometer stayed at zero when driving. So I will also check if I have wires also left unconnected.

So I worked on my car, and filled it up with transmission fluid. The car still will not go fast in Drive. I still have to put it in second and third gear to get the car moving. My speedometer stays at zero no matter what.

I did change my right front strut. So now I have to get that balanced.

What am I to do?

Take this to a transmission shop for diagnosis. If you replaced the right front strut all you have to do is get the car aligned.
