i resently swapped a 97 ls engine into my 98 civic hatch and it wont run.
the engine was pieced together from many different engines...the list consists of:
95 ls head with 97 ls internals, 97 ls block with 97 internals, 97 itr intake manifold, 96 ls throttle body, 96 ls distributor, ls fuel rail, 97 itr fuel press. reg., 96 ls injectors, 97 ls fuel pump, 97 itr crank pulley, 97 itr exhaust manifold, ls tranny, b16 flywheel, ls clutch, itr starter, i used a single ply of a stock ls head gasket, 96 ls ecu and i modified my stock wiring harness usind a haynes manual for both vehicles.
ive done compression checks(about 200 in all cylinders), ive got spark, ive got fuel(47psi), i set the timing, tried the distributor in every single position, adjusted the valves(.004 in and .007 ex) i checked every sensor on the engine a hundred times, the 3 in the distributor and im stumped!!!
ive had numerous people look at it and weve tried different thing but, still nothing. the engine fires right up and holds a nasty idle and as soon as you touch the throttle in bogs and stalls or misfires
please, please anybody. ive been working on this for over a month now and it is my only mode of transportation. i need to get this thing running!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
