i just bough a 1984 733i yesterday, with a apparently clean and smooth engine and a super clean and straight white body.
main probs are a/c wont even blow exept in defrost mode.
engine is missing stock airfilter box with what appears to be a 15 pin sensor ???
and although engine idles and throttles great and MOST of time is very smooth and effiecient with transmission--- it often refuses to RE-ACCELERATE after a breif deceleration-- example - if i go from 40 mph to 80 - let off pedal to 70 and then soon try to push pedal back to 80. engine and rpms dont respond and i have to wait till car gets to around 40 again for pedal/throttle to engage and engine to accelerate again.
similar problem occurs occasionally in all ranges.
ANY ADVICE, pix or linx appreciated.
