Hi
I have a Cavalier 1996 2.2 4 gears.
I have a glitch that occurs from time to time, can happen week other day ... there is really no specific time.
Also fault occurs not turn on lamp malfunction.
The problem is such that when I cruise at 60 mph the rpm is at 2500 instead of 2000 + -, in this situation you can not fix the cruise control. When rpm Normally relative speed cruise control works, during all this time there is no lamp to malfunction.
After consulting with several machinists Most say that one Hslonoad invalid, do not ever work here.
The question which one to faulty and do ever you have any such a problem?

* Please mention that I changed twice oil and filter.

 

Very little information. From what you posted I'd say there may be a ground problem.

 

translator please.

 

I do not have too much information ...
When I'm at a constant speed, rpm does not match the speed.
Change is 500 rpm above should be.
Probably one of Solenoid not opening or closing passage oil.
The question is which one?
There are other missing information that could help?
