Could just need a tuneup. Plugs, wires, etc. How many miles? Is the check engine light on?

You can retrieve the codes yourself with just a paperclip.

You need a coolant temperature sensor. (Yes, that does sound ridiculous but it's true).

Your car has two temp sensors; one for the gauge and one for the computer. Replace them both. The sensor for the computer is malfunctioning, telling your computer that the coolant temp is wrong. This makes the computer alter how your engine runs (and why you have to hold the accelerator down to crank it). These are about $10 a piece so it will be cheap.

Also, you should pull the throttle body and clean it thoroughly. It will likely be gunked up pretty good.

I just went through this with my 1995; I replaced the TPS, the idle air control valve and cleaned the throttle body before finally finding out about the temp switch. Good luck!

Suggested Repair

Replace both coolant temperature sensors (the gauge sensor and the computer sensor) and thoroughly clean the throttle body. Stored codes can also be retrieved with a paperclip if a scan tool is unavailable.

Conversation Summary

A 1995 Saturn SL 1.9L DOHC sedan hesitates when accelerating and sometimes stalls at stops, requiring the accelerator to be held down to restart. The owner reported about 16,102 miles, tried fuel treatments and injector cleaner, replaced the plugs, wires, PCV valve, and fuel filter, and noted a cracked sensor connector near the air filter. The service engine light had been on but went out after fuses and relays were removed and reinstalled. One reply suggested a tune-up and retrieving codes with a paperclip. Another advised replacing both coolant temperature sensors and cleaning the throttle body, based on the same symptoms on a 1995 Saturn.
