Check for a broken intake air boot... usually a crack develops between the "accordion" sections of the boot(s).
Also check the little brown ground wires that attach to the cylinder head (some are brown/blk).
To test the fuel injection system (fuel pressure regulator etc), you need a Digital Volt Ohm Meter to do voltage
and current draw (through the regulator) tests.
Check your ignition wires for arcing & oil contamination at the spark plug ends... distributor cap and rotor also
need to be checked.
