STARTS STALLING AGAIN WHEN GOING UPHILL ON HIGHWAY, IS IT THE CATALYTIC CCONVERTER, OR FUEL INJECTORS ?? PLEASE HELP.
Any number of things can cause this problem.
Yes, a plugged catalytic converter is one of them. Also low fuel pressure, inaccurate mass airflow sensor (MAF), corroded ignition coils. The key to starting diagnosis Is to get the system scanned for codes. Most of the large national parts store chains will do this for free (Autozone, Murray's, etc.).
If a code like p0300, then misfires are your problem, so checking ignition system(coils) would need to be done. If other codes, then that system will need to be looked at.
If no codes, then would look more to fuel pressure. Usually these things or a catalytic converter will set a code. On the 'How-to, tips, pics' page of the site, there is a good picture of a corroded ignition coil that may help. Click the link 'ignition coil and plug wire inspect'.
Just pull off plug wires 1 by 1 and inspect. This is a simple check that may help. Let me know what you find and i will try to be of more assistance.
