Plenty of problems!
A bit of transatlantic advice needed if you dont mind!
Sorry if this is the wrong place for it, but I couldnt see a "problem page" on the forum.
I'm driving a 1996 European 1.6 with a Greddy TD05 turbo, trust intercooler, fuel pressure regulator and 1.8 injectors.
I have been having a lot of problems with detonation in the engine lately. It was first mainly in 4th and 5th.
First thing I did was drop the timing way back but the detonation is still there.
I thought that it might have been the spark plugs as the ones that I was using weren't the right ones for a turbod car.
No joy with the spark plugs changed them on Sat night and the engine is still detonating in 4th and 5th.
I don't know what to do at this stage. I put in a boost gauge and its only running at 4 Psi. the set-up I have should be good for 8 Psi.
Two other problems as well, when the car is cold the fuel delivery isn't great into the engine, it seems very "chuggy" for around 30 seconds and then its ok, its like as if the choke is very slow coming in.
This only really started happening when the fuel pressure regulator went in.
The AFPR is set to around 46 Psi when the car is idling.
About a week ago the car started sounding unhealthy, as in the revs would drop to around 300 and then shoot up to around 1200 to stop it from stalling, and then drop back down.....
Well there is my short story, any advice welcome and appreciated.
