Where is the choke sensor on a 1991 Oldsmobile ciera 3.3L
under the hood On the passenger side against the firewall. Its at the far left upper portion. It is black has a connector and a small hose going to it. Two screws hold it into place. The heads are bolt head and very small. about 6-7 mm head maybe 1/4.
The map sensor is located on the intake manifold on a 1996 Olds Achieva 2.4 liter. It is in the center of the intake manifold.
I've looked also and have yet to find it, service manual doesn't say specifically that it has one. Having just spent a Saturday looking for it I don't think it exists. My problem came down to the MAF sensor.
Yes, My 72 Olds Cutlass convertible came with the light option package which included a map light in the rear view mirror.
the map sensor is on a bracket between the firewall & the inside valve cover. it has a 3 wire plug on it & a vacuum hose that goes to it.
bad oxygen sensor bad map sensor
Try changing the fuel filter and the map sensor.
There isn't a MAP (Manifold Air Pressure) sensor on your car. There is however a MAF (Mass Air Flow) sensor which is located on the air intake hosing slightly ahead (towards the passenger compartment) of the air filter housing.
check your fuel presure regulator Might be as simple as a fuel filter. Or could be many many things. Good to start with this and vacuum and potential bad sensors like EGR or MAP sensor. If your fuel pump (inside the gas tank) has been changed recently, then that is ruled out. I had the same problem. It was tested as being the Map sensor. The pistons were firing out of time and the engine ended up running rich. The catalytic converter ended up becoming clogging and turning cherry red because of the rich mixture. I also had a 1992 Olds Cutlass Supreme. I have the same problem with my 91 olds, its in the IAC motor, take it out and clean it.
It uses a MAP sensor.It uses a MAP sensor.
a map sensor is a manifold absolute pressure sensor.
if it has a 3.3 there is no map sensor
