Yes I have searched this forum as well as many others. That being said...
I have a 1997 Japan spec spi with ac / air conditioning and an mpi block etc.
I imported it not too long ago and have spent hours fixing issues. I have gone through and replaced all the vacuum lines, the lambda or o2 sensor, plugs, distributor cap / dizzy, wires, reset the ecu / computer, cleaned the butterfly / throttle, and have obviously changed the oil. Oh and I have also changed the oil pressure sensor but with the wrong type so the dummy light comes on fairly regularly.
Ok, after I just replaced the vacuum lines and lambda it solved a bucking problem I had at highway speeds. However now when I accelerate the engine pauses then smoothly accelerates. It feels like a hesitation or delay right after I press the gas pedal. Happens at all speeds even from a dead stop. Feels like it would die or stall if I pressed the gas to the floor from a dead stop and a buck if I were to press it from any moving speed.
Any suggestions?
Thanks!

Bahhh,
I spent another hour searching forums and decided to double-check my own work again.
I found that the vacuum line I made was a wee bit too short from the back of the manifold to the MAP sensor. It had a pinch on the end that went to the MAP. I replaced it with a longer line with no pinches and presto! Problem gone!
Thank you for your replies and I have to thank the forums for help too!
