Having problems with your 2003 Buick Rendezvous ?

On a 2003 Buick Rendevous the computer keeps coming up with a code of P1374. Have check both of the crankshaft sensors, the 24x has an input of 11.15 instead of the suggested 12 volts. Nothing else obvious is wrong. The car seems to have an erratic miss at midlevel RPM like low feul mix, and it shifts about 1000 rpm higher than ususal. where to next?

Answers :

Timing Reference High Resolution Signal A ( No Pulses) This is a misfire code so try this info. This info is where your mechanic would be following.
\015\012The following info comes from a code reference guide for troubleshooting.
\015\012Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
\015\012A random misfire code usually indicates a vacuum leak or bad gas.
\015\012a misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.
