Which crank sensor ? yours has two .
Crankshaft Position (CKP) Sensor A
Center front of the engine, near the base of the engine oil level indicator

Crankshaft Position (CKP) Sensor B
Center front of the engine, near the base of the engine oil level indicator
Engine Oil Level Switch

Center rear of the engine, in the right hand exhaust manifold

First of all, which cooling lines aren't hooked up and why not? Your engine computer uses temperature as part of it's program to determine how much fuel to give the engine so maybe the computer thinks the engine is cold. If it thinks the engine is cold it will add extra fuel to richen the mixture like a choke used to do.

Second, have you read the codes and what are they? Your car should be OBD1 which can be read without a machine. Under the dash near the steering wheel you should see a long skinny plug-in. It will have 2 rows of pins and 2 of them should be marked with an A and a B. Turn the key to the "on" position and put a ;iece of wire between the A and B. The engine light will begin to flash in a sequence of long and short flashs. The long flash is 10 and the short flash is 1. The first code you will get it 12. This says the computer is working. Then it will flash other codes. All your codes are 2 digit numbers and it will flash each code 3 time, so you will get 12,12,12,?,?,?,12,12,12. When it is done giving you codes it will flash the 12 again. To erase the codes, simply unhook the Negative battery cable for a minute or so.

Once you have the codes simply type "91 Cavalier engine codes" into your search engine and about 100 pages of sites will show up that will give you the code printout. Hope this helps.

under left side of front hood sounds like air pump for rear struts a leak in the suspention system & u may have a antenna issue also un plug antenna in trunk & listen for motor under hood if it thear disconect air pump under hood.

The crankshaft sensor is an important sensor for regulating spark and fuel injection pulsing.

I don't know what an 'engine sensor' would be besides the crankshaft sensor, specifically.

Engine sensor is a general term.

Hi welcom to fixya. A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark ****** than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.
To replace the knock sensor:

• Disconnect the knock sensor wiring connector.
• Then, unscrew the sensor.
• Remove the knock sensor.
• Reverse the procedures to install the part.
• 15 ft.lbs.torque
• hope this helps.Thank You for using fixya..iluv2fish.. Ray..
