I'm new the forum, and love it. Almost all the problems I have ever had with my car has been already covered here. Most recently I had a problem with the car surging at stops and got that fixed on advice by doing as Ranger did, and changing the spark plug wires.
Well a few nights ago an entirely different problem hit my baby (1998 Cadillac STS). The car was driving incredible as usual and I was on the acceleration ramp getting onto the highway, I gave the car a little more gas to speed up and get in before the traffic and the car just shut off. I was able to get it to the shoulder with the speed it was going at. At the shoulder I tried to start it up again, and it started fine. It idled perfect, so I put it in to gear and thought it would be fine, I was wrong as soon as I gave it gas the rmps started to go crazy up and down, the car started going then stopped almost like it was stutering, as if something was letting it accelerate then taking all power away, then trying again. I shut it off and tried it again, but left it in park this time, and the exact same thing happened when I gave it gas. If I put my foot all the way down on the gas, it will just rev the rpm's all the way up then drop like a rock, go all the way up then drop like a rock, all the while the car is shaking like crazy.
If any of you have ever experienced anything like this before, or have any ideas on what it could be please help!!!
Even my mechanic doesnt seem to know what exactly is wrong with the car.
Thanks everyone for your help, I gave it to my mechanic and even he seems to be dumbfounded by this, he originally thought it was something to do with the fuel line, but now says it is not the fuel line or filter, he now believes it is the ignition module. I had the Fuel Pressure Regulator changed a few months ago, because of another problem with the car surging.
I checked the codes and the only one that comes up as current is RSS C1762 (Left Rear Position Sensor - Input False), but I doubt that has anything to do with my problem. Do you guys think it's possible for it to be the ignition module itself? I'll have to tell my mechanic to check the charging system. But thanks again for everything. I really dont want him to change the ignition module and have it be something else especially with the price of these parts. Any other suggestions?
I just talked to my mechanic there is a little bit of a hold up getting a hold of an ignition module, but hopefully we are able to resolve the problem, its a good think i've built a good relationship with the mechanic. So I will only have to pay for the part, he said it only take like 15 minutes to connect. Makes me wonder why GM wanted to charge me over $1000 dollars for this job.
Anyway I will post tommorow to say if it solved the problem. Thanks again.
Well my mechanic got the part (ignition module) installed today, I'm happy to say everything is working great again. Thanks everyone for your help. And hope if anyone else experiences the same problem, they have an idea of what to do now. I'm just really thrilled now that my caddy is back, and life is back to normal.
