jimpon Posted April 21, 2005 Share Posted April 21, 2005 whilst driving down the road at varying speeds it feels like the car loses gas flow until I step on the gas and the turbo kicks in, car runs fine for a few secs then the process starts over again. any Ideas Jim Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted April 22, 2005 Share Posted April 22, 2005 I'd start with fuel filter. If that doesn't help. Timing...on turbos I believe it is 20' BTDC. You have to hook the green connectors together ...which on my GL-10 are under the steering column behind a panel. There are two black ones too...don't connect those. They pull codes from the computer. Then check the cap and rotor...and wires. Or it could be your turbo crapping out..that's almost the worst case though. Pull the intake off the top of your engine and look for oil...well I guess you would be burning it too...does your car smoke alot? Sorry for the fragmented reply...hope it helps though.

Skip Posted April 23, 2005 Share Posted April 23, 2005 Jimpo, HTi said "green connectors" not green wires The "story" is the ignition timing on your car is controlled by the ECU (Electronic or Emission Control Unit) When you want to set the static timing or base ignition timing you have to tell the ECU you are doing so. Plugging these connectors together tells the ECU this. If you are not party to this info, your statement "timing is on the mark" is a bit bogus. Allot of surging can be caused by fuel octane rating. The ECU is sensitive to the knock sensor and will retard or "pull" timing advance until it does not sense knocking. Try another brand of high test. If the car accelerates normally when the turbo is showing boost I would have to rule out the fuel filter scenario as this is when the most fuel is needed. Have you ever seen the CEL (Check Engine Light) on? Link to comment Share on other sites More sharing options...

Cougar Posted April 24, 2005 Share Posted April 24, 2005 I think the engine timing is under the control of the ECU until the green connectors are tied together. If you saw 20 degrees with them apart I think that is normal. The problem you are having may be due to a weak fuel pump. I would have the fuel pressure checked.
