Well i just bought a 95'accent 5- speed. with the 1.5L engine. When the engine is cold it has trouble starting (takes 2- 4 trys before the engine starts) and when it does finally start the engine is really hesitent to rev up. after i let it run for a few minutes and it gets hotter the hesitation goes away and it seems to run fine. If i start it when the engine is already warmed up it starts fine. Im thinking it may be the Coolent temp sensor for the ECU (below the thermostat housing).... or maybe a problem with the fuel pressure regulator.

Also i noticed that at around 4000 RPM when the power should be coming on stronger, it looses power before it should. this occurs in every gear. it actually has more power at 3500 rpm then 4000 rpm. again,,, may this be the FPR?

thank you guys in advance for the help
