Hi,

Can anyone advise me on how to test the functionality of the MAP sensor on a 1993 cinq ?

Many Thanks

Hesitation under low revs,....so bad that the car jerks under low revs between 1st and 2nd gear.

Ive replaced the coils and the Lambda probe but no joy.

Any ideas ?

When cold only or also when hot and does what RPM are you changing at make a difference?

Unscientific way. Remove pipe from MAP end, put finger over end of pipe, rev engine. Pipe should stick to finger.

Vacuum then OK

Replace pipe on MAP, remove from TB end. Fit a syringe to the pipe.With engine idling, pull on syringe revs should rise.

Cheers
