I have done alot of work on this thing up ad running due to dry rotted and cracked air intake system.

Runs like a champ on interstate and gets great gas mileage. Ran from jackson , Ms to tampa florida at about 80Mph with air hitting 40 degrees between 28-30 MPG. Around town its closer to 20 MPG.

Question is I get a CEL only on cold starts, saying Map sensor last Tiem I checked it.

Only thing I have noticed is a hissing sound from fire wall around steering column area.

Only other issues are :

ABS Light , Blinks once

When you break hard feel alot of vibrations left to right on hard breaking .

lots of squeaking from right wheel well , I think its the strut as it does it when I get in and out of the car . already replaced upper control arms and ball joints that were worn out.

 

double check your intake and all vacuum lines...especially the one to the MAP sensor, probably the "hiss" you hear. who cares about the ABS light blinking...as long as the car stops, put black tape over it

 

will run back over all of them ..

but the hiss sounds more like it is coming from alo tlower than Map sensor location
