Hesitating while accelerating

Postby LvX » Thu Aug 04, 2016 6:34 am

Hi All,
i'm restoring my st185 that was sitting in the garage for almost 10 years, after fixing a broken ecu and rewiring the distributor the car now runs fine.
the only problem i'm facing is that the engine does hesitate a bit while accelerating, i don't know how to explain it in english, but if i'm at idle (which is good) and i floor the gas, the car tend to stall and then rev.

If i give it little gas the car doesn't do it.
It seems to me like a lean situation, i've checked the manifold for leak and fixed a few one but nothing changed.
I've also tried to adjust the tps following the bgb without success.
Please help i'm running out of ideas

Double checked ignition timing and tps, it's all perfect now, also found a little leak on the 4th injector, removed and fixed

but still this annoying hesitation :bangshead: :bangshead:
