Question about 1983 Cadillac Eldorado
My car is a 1983 Cadillac Eldorado Touring Coupe....... The car seems to me to have idle problems, i was at a stop and the car while i was holding down the break decided that it wanted to go anyways and knodged up a bit on its own while im holding down the brake. Another problem is that it cannot make it up hills and starts to deccelerate. Scary feeling when you got a bus behind you.If you drive it on flat ground seems to work ok i never felt properly yet so im not sure if its relevent. but as soon as i reach a big slope and for a long time i will not make it unless i got a good start to the hill, but off the line at the street lights up a hill i will not make it. The brakes as far as i know i got them fixed by mechanics i dont trust and they seem to not brake properly. i mean as im holding down the brake all the way and i dont seem to get much of a response.I understand its an old car but i havent experience this before. if perhaps you have any ensight on these problems i would love it , as this is my baby and dream car i dont want to go through the trouble and find a new one. these are rare cars.classics. thank you
Sounds like the ISC ( idle speed control ) motor and TPS ( throttle position sensor ) are in need of a synchronizing adjustment. If one of the adj is off is throws off the other. UNFORTUNATELY the HT4100 had a reputation for leaking intake manifold and head gaskets,whichic also could the problem. Any service lights coming on ? As far as going UPHILL power loss, first thing I would do is replace the FUEL FILTER . road test and note any difference. Now the brakes. Regardless of the vehicles age, done properly and with properly operating equipment should stop like new. Either done incorrectly, or poor quality parts. Many factors. The car is a keeper is handled properly. Hope this helps
