map sensor

[dreamer1uk]

Hi,

The 93 D/P engines do not have MAP sensors. They have MAF.

Is the CEL on? Lets start with the basics first

Like I said guys I,m in forgien waters here......I,m a welder by trade ,no car sence at all.
So what is the CEL and how do I turn it on?????

[dreamer1uk]

Hey,

The CEL means "Check Engine Light'. Usually if a vehicle is running that poorly, it should pop the CEL. Even if the CEL isnt on, still have the vehicle checked for codes.

If i were you, id be checking all my vacuum hoses, electrical wiring, and even the timing belt and checking to see if they havent decayed and such with the vehicle been sat for so long.

And welcome to the forums!

Ok,no the CEL is not on,I just finished a 12 hr. shift.....Tomarrow is a off day,maybe I can check all the hoses and conections then....TNX for the help and the welcome....
