cleaned throttle body, made bugger all difference.
My latest theory is......
Engine is NF
New fuel pipes are off an NG (80/90 car) and are shorter. The pipes are a bit "stretched" but I managed to get the injectors to seat into the inserts, and the other end onto the metering head.
The injectors are held in place by a rail. However, as the pipes are a bit "stretched", some of them may be pulled over to a slight angle, and may be letting air in there.
I know everyone has said that already, but I tried squirting WD40 around the injectors, but the manifold is in the way. I also thought that an air leak would manifest itself as lean running, and wouldn't idle very well.
HOWEVER, this car has KE-JET which has a lambda sensor which can correct an imbalance in mixture.
So if it were leaking air in, the lambda sensor would sense lean running and tell the injection system to chuck more fuel in.
My other revelation will be to squirt carb cleaner directly onto the injectors one by one, as carb cleaner sprays a jet of liquid, whereas before I was using WD40 in a mist form, or a blowlamp, and neither are very directional.
That's my thoughts on the matter.
Anybody agree or disagree on my theory?
Only thing is if I find ot the pipes are too short, I'll either have to find some off an NF engine (bloody impossible), or get some made up by goodridge supplier (merlin motorsport at Castle Combe, 10 miles from me).
More bloody cost!!!!!!
