My buddy has a 91 talon with a '93 2g3... engine not sure exactly. 2 liter dual cam non turbo. Anyway, the idle is not steady. When the car is started it jumps to 2000rpm then it'll die down but bounce from 1000-1800. Im thinking IAC or MAP. What do yall think?
One more problem is when coming to a stop on the brakes. When at about 15mph there is a hard thud, not very loud but everyone in the car can really feel it. New rotors and pads are coming once he buys them. He knows nothing so im stuck doing the work. I do get some parts in return.
Being a honda guy im totally lost in dsm world. Any help would be great.

dsm dont have a map sensor from the factory, check the iacv and for any leaking vacum lines as far as the brakes check those and the suspension components if its a automatic could be the tranny also

also the biss screw could be off messing with the idle its a big screw on top of the throttle body that sets your idle

the engine is from a 93 lazer n/a. i was thinkin tranny origionally for the knocking sound. ill tear the suspension and brakes down when i get some free time.
