Hi, what all did you do on the tune-up? Changing plugs is a small part of a tune-up. Did you get the plug wires back in the correct location? Are there any trouble codes? Use a gage and check fuel pressure.

You don't need anything special to check codes, your obd1. To check mil codes, you can place a jumper wire between A & B terminals of datalink connector. Then turn the key just till the dash lites come on, no further. The mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

Also, some of the national brand autostores used to loan out a fuel pressure gage. You can call and ask.

If the problem is temp related, check the coolant temp sensor.
