my car is a 95 del sol, running with a b18c that we swapped in about 2 weeks ago and i havent been able to get it to run right. the car hesitates and bogs when at normal operating temperature mostly under ~5k rpms and sometimes high rpms as well. before the car gets to normal opperation, it runs fine with ~0% hesitation (havent messed around with it much when cold).

there are no CEL's. the cap, rotor, distributor, plugs (gapped to 1.1mm), air/fuel filters are all new. the plug wires worked fine on my old engine (b16a), though i may replace those too. all grounds are intact and tight, unless there is one that i missed. i got the one on the valve cover and the transmission, as well as the one to the starter.

i messed around with the timing a bit, but nothing seems to help. i havent taken a timing light to it because 1) dont know where my dads is, 2) dont know how to do it, but im sure its not hard.
