rough idle please help

[heyhi]

My 93 j30 been parked for a year and i wanna get it on the road. Before I parked it it ran rough. When stopped at a stop sign it would stall and when hitting the gas it would hesitate. I checked the spark and changed the plugs.There were no codes on the ecu.

I dont know where to start looking. can any one help me where to start and gimme specs to check for. i wanna check the maf sensor and coolant temp sensor but i dont know what voltage to look for .

is the 93 obd 1? im thinking of getting the consolt. I had my timing belt changed 2 years ago.Ilove this car and c ant afford to bring it to a mechanic please help me out.

Ok change the fuel filter with an OEM one.

Check the transmission fluid

Change the oil/filter

clean the MAF sensor, The voltage won't matter what its at sometimes its the circuit board that goes bad a after the years

What about the spark plugs when were they changed?

1996+ is OB2 so so 1995 and below is OBD1

The Major thing that is causing all the problems is the MAF but doing the above is good for the car after its been sitting.

There is also the tires that might need changing due to dry rot, the hinges on the door that might need to be greased, A car wash...

You know the basics But good luck.

OEM spec plugs ??

And ditto on cleaning the MAF sensor.
