Information RE: 4age hitting gas too quick means engine stalls - what is the issue?
If you cannot drive the car then it is not possible to put the engine
under load. If there is a restriction to flow in the fuel line (kinked hose,
flattened hard line or partial blockage) it is possible to have good pressure
at idle but low pressure and fuel starvation under load. A fuel pressure
gauge can be used to check while the engine is running, as opening the
throttle quickly puts load on the engine for a second, and the gauge will
drop if there is a problem. But we can leave this until later Smile

First you should check the engine timing in this order...
1. Take off the top timing belt cover and check the dimples on the cam
pulleys line up with the marks on the backing plate. When the marks are
lined up, make sure that the engine is at TDC (timing mark on crank
pulley at zero degrees on the timing scale marked on the bottom timing
belt cover). If the marks do not line up you will need to adjust the belt.
2. Check and/or adjust the tensioner for the timing belt if the timing belt
is loose. You will need to be able to turn the engine by hand using a
socket on the crank pulley bolt. I don't know if this is easy on an AE92 ?
3. Check the ignition timing with a timing light. You need to be able to
keep the engine speed steady at around 850-900rpm. DO NOT bridge the
diagnostic plug/box). The timing mark on the crank pulley should hover
around 16-17 degrees at idle, and increase with engine speed.

Once the engine timing is confirmed to be correct, if the problem still
remains we can look at other possible causes.
