My 89 Honda Civic 1.5l dont put out the power it should?

get a compression check done on all the cylinders to see if you're losing compression. and what do you mean by "timings"?

Check out your breather elements. Your air filter. Maybe a new intake would solve the problem. I recommend an AEM short ram intake.

do you have the firing order right on your spark plugs?

i would get a compression test you could even do it yourself buy a compression test guage and if all is good i would get the injectors cleaned or replace them Displacement : 1,493 cc (91.1 cu in) Bore and Stroke : 75 × 84.5 mm (3.0 × 3.33 in) Rod Length : 134 mm Compression : 9.2:1 Power : 92 hp (68.6 kW, 93.3 PS) at 6,000 rpm Torque : 88 ft·lbf (12.2 kg/m, 119 Nm) at 4,500 rpm Valvetrain : SOHC (4 valves per cylinder) Cam Gear : 38 tooth Piston Code : PM3 Fuel Control : OBD-O DPFI and OBD-1 MPFI Redline : 6,500 rpm, 7,200 rpm rev limiter Head Code : PM5 ECU Code: PM5/P04
