The car idles rough and stalls when you start it up cold or hot. Just changed the air filter on it. Check engine light is on but don't have an OBD1 scanner. Any suggestions?

Check it for tune up and vacuum leaks

Trouble codes are retrieved from EEC system through MIL (CHECK ENGINE light) located on instrument panel. MIL is used with Diagnostic Test Connector (DTC). See Fig. 2 . To retrieve codes, use the following procedure:
Turn ignition key to ON position. Disconnect the diagnostic connector, located near starter,in engine compartment.Fig. 2 . Jumper between Blue/White and Grey/Blue terminals as indicated in illustration, and wait 2 seconds.
Remove jumper wire and reconnect diagnostic connector. Record DTC, MIL flashes.

READING CODES
All trouble codes are 2-digit numbers. PCM outputs codes one digit at a time. These codes indicate current faults in system and should be serviced in order of appearance.

Scan tester, if used, will count pulses and display them as a digital code. If using MIL, trouble codes are displayed as light pulses from CHECK ENGINE light. When using MIL, pay attention to length of pauses in order codes correctly. See Fig. 1 .
Pass Codes
Code 55 indicates system passes that portion of test. If Code 55 is not retrieved, proceed to CIRCUIT TEST corresponding with trouble code that is output.

CLEARING CODES

To clear codes from PCM memory when using MIL (CHECK ENGINE light), disconnect jumper wire and reconnect harness connectors. If using scan tester, follow tool manufacturer's instructions. If problem has not been corrected or fault is still present, code will immediately be reset in PCM memory.

An OBDII reader will not work
need an older scanner

check with local repair shops most they still have it and should be able to get the codes for you

Just put new plugs and cap and rotors on it. Still stalls at idle and seems to be starving for gas when under a load. Changed a vacuum hose that was cracked. Still stalls. Any other suggestions?

Staving for fuel
check for fuel pressure
replace fuel filter too

stalling issue check MAF sensor
that also may be a cause of a lack of performance under load too
