It is a pain but you can replace the sensor without removing the intake.

Did you also check the engine speed sensor?

well its a 86 does not have a speed sensor,but its verry strang that i can let it run for about 10 min. first and it will not die out.ok tell me how i can replace the temp sensor whith out taking off the intake manifold,i can see yhe sensor but can not put my hand on it. P.S will a temp sensor cause the motor to shut off like its not getting spark,somtimes it starts right back up somtimes it takes a while.

I don't think it will make it die like no spark.

I think you have a power stage problem or soemthing like that.

You have to have small hands and be able to move them good.Then you can get to the sensor.

Does it happen when you let your foot off the gas and it is supposed to return to idle?
