Gt Starlet Engine Problems?

[starwand]

Hi,

just the other day i went for a run with my car. I was running it pretty hard. I drove for about 20-30 min. After awhile the car started bucking as if it want to close off. I stoped the car and turned it off when i started it again ..it was running good , then it started to do the same thing. i nearly made it over a hill it sounds as if it was missing out (not sure). and it kept bucking. There was a great lost of Power

Can anyone give me any ideas as to whats causing this problem.

I changed the plug wires baught new ones and checked the plugs but they seemed ok. Also the Coil wire.

It doesn't happen when the car is cold when i run it for about 30min hard it happends

i asked a mechanic he was telling me that the Turbo carries a log it's not to worry about? that kind of thing happens????? ;)

Is that so???

Hey mate have you donr anything to your car modifications wise? Sounds like you might be hitting fuel cut this happens when the turbo produces a boost pressure over 12 psi

Could be fuel mate something in the tank what plugs are you using?

[starletsy]

From what you have told be mate then it will be the plugs get some decent NGK's in there the number is BKR7EVX

are you getting a knocking sensation? it could be that the car when hot is thinking your getting a nock (a supersonic shock wave on top of your cylinder) and then retarding the ignition so much that it bucks.

have a nice day
