Hello everybody.
I have a 1990 Astra (1.3L engine with PB - 2E3 carburettor), which gives out these two problems:
1) The idle is quite rough. Not very badly (it doesn't affect high revs operation) but enough to make the bodywork vibrate in a very unpleasant manner. Uh!2) When sun shines and the body gets hot (imagine a hot summer day), attempting to start the engine results in 2-3 seconds of normal operation, then the engine dies out. The only way I can drive my car out of the parking is to keep my foot on the gas (thus giving the engine high revs) for 20 secs. Then it operates normally and idles well (see problem no. 1)
What did I do:
Purchased and used a 2E3 service kit. Replaced all gaskets, pumps, needles a.s.o. in the carburettor. Replaced spark-plugs, distributor cap and rotor by new ones. Took it to a garage and had the ignition timing and compression measured. They all checked out OK (that's what they say). Gave the intake manifold gasket a visual inspection. It looks quite well (no stains, light green, like new). Been a good boy, so Santa would fix my car :-) But no, problems are still there.
Questions:
1) Any chance these 2 problems are related? 2) Should I suspect a faulty electrical component (HT wires, ignition coil)? They're not very cheap, so replacing them blindly wouldn't make me very happy. 3) Any way of checking the intake manifold gasket? I mean, without removing it.And finally, please help. I'm quite at the end of my ideas.
Thank you in advance.
