Replying to: rebeccat (Dec 19, 2007 6:38 pm) Regarding only the AC not going to Auto. This many times means the AC system has lost freon pressure. The pressure and/or temperature sensors in the AC system will NOT allow the system to switch on when it has leaked freon out. When the system is in ECON mode, the AC does not run. So, with no freon, the computer automatically shifts it into ECON mode.   Find the leak, fix it, recharge the system.

Having a few problems with my caddy. Rough idle, surging at 30 to35 mph then smooths out. Have been told that it might be the electronic throttle positioner. This vehicle only has 96,000 miles on it an is in show room condition. I've changed the plugs,wires,cap,rotor. Also the catyletic convertor changed out,all the filters,except the fuel filter. only run premium fuel in it. It has The 4.9 V-8 engine in it. Some please help me in this matter. I'm stumped and almost ready to take it and have a diagnostic ran. There is no service engine light on or anything telling me if anything is wrong. Can it be the E CM has gone faulty?

Replying to: toneyg (Dec 31, 2007 2:47 pm) Does this car have Throttle Body Fuel Injection?   If so, there are 2 air passages in the bottom of the intake that clog with carbon and cause dirveability problems such as you are having.   These passages can be seen by looking straight down into the throttle body. Use a probe or screwdriver to clean these passages and your problems might go away.   Otherwise, yes, the idle control and/or throttle position control (some cars have both of these) can go bad and cause problems. I'm not sure these type problems would continue until 30/35mph. If these are the problem/s, I think replacement is rather simple, take off the old ones, put on new ones. BUT, getting them re-set so they work well is a real mess, best left to a mechanic who understands them, or has factory service manual to follow the procedures.   There is also MAP sensor could be bad or the Exhaust Gas Recirculation (EGR) valve that could be also clogged or bad.   Finding a mechanic with experience on this age Cadillac might be your best bet to narrow down exactly is your problem. Or, if you was to pursue it yourself, buy the factory service manual, not one of the after market ones.

Replying to: bockscar (Dec 06, 2000 1:11 am) I see that asked decades ago, but I had the same issue, very frightening. It was cured by fixing my loose engine mounting. Sounds odd, but it fixed the issue, never happend again.

Replying to: noyesfranka (Jan 06, 2008 12:50 pm) Your problem could be a bad relay, or your are grounding out to make the circuit complete. But more than likely it is your relay
