I have just bought this 98 eclipse gsx,as i was driving one day my car was climbing a hill fine as i reached middle of the hill i lost my boost and car started a lil after that wanting to stall luckely i was close to my house, the car was basically undrivable with no boost and car wanting to stall , we found out it may be the idol air controler so we went and bought a new one,installed the new IAC and it ran just fine,after that we installed some high performance plugs and wires after installation we tested plugs and wires to see if it ran ok ,car ran just fine,couple days later i was driving up another hill as i was being a lil speed deamoned as usual, i lost my boost again i thought oh damn did it again, but this time the tach was fine but the turbo guage was acting funny as i accelerated all i get is a shppshh outa turbo instead of reg. sound like the turbo was resisting the boostvery low boost sound :( such a nice car i gotta save it. or it could just be i busted the damn IAC again idk ill try her in the morning ill know wen the engine is colder.

Hi 98gsxjake,

Start the engine, rev and release while watching for any pressure escaping from the hoses.

If you have a boost gauge, low pressure would be burst hose or the turbo is bad.

Remove the air cleaner hose at turbo unit and try to turn turbines by hand, it should freewheel, any sticking means the unit needs servicing, repair or replacement. DO NOT attempt with hot engine.
