ENGINE HARD START AT FIRST

1998 Saturn SC1

Engine Performance problem
1998 Saturn SC1 4 cyl Front Wheel Drive Manual 130574 miles

I have a staurn 1998 saturn SC1. And I have a problem every time I start it I've replaced the O2 sensor, and bought a EGR for 92. So its starting to get expensive, the guy who had it put on a new exhaust it has a cold air intake, but I can't hardly start it sometimes it only happens sometimes, such as when its cold I have to put the clutch in and push the gas in ALLL the way thats a terrible waste, but it starts and then LEVELS out completely fine. We got a number of codes but no " Check Engine Light" at all the computer is not ready we tried to pass it through inspection 3 times. All failed the OBd II test. We reset it by unplugging the battery for an hour, then we tested no codes
then we went back the day before inspection checked it again and got the replace EGR which has been done. And we have yet to take it up there but I fear it is going to fail once again, can anyone help me with this? Hard start. And it would also be nice to help with one more thing as well the engine temperature GAUGE does not WORK AT ALL! This is annoying as I wouldnt know if it over heated only by visual and touching the engine. All I would need to know is how to replace/ reconnect / fix this problem as Im pretty good with the car and helped put the engine in. So thank you!

Sound's like you have a bad coolant temp sensor with what you describe.I posted a diagram of where your coolant temp sensor is.It's screw's into your head pretty common for them to go bad on that model.Make sure you get a brassed tipped one the plastic tipped one's crack.Also inspect the connector going to it if it's corroded then replace the connector as well.Make sure the engine is cold you will loose coolant.Let me know what you find.

THANK YOU SO MUCH also is there anything I can do with the computer probelms? Its not a bad computer. Its just need the *drive cycle* and I heard I might have to take it and get this done by a pro for 89.99. So. Any fixes for the OBD II?

If your talking about reseting your monitor's then take care of your coolant temp sensor problem make sure all your code's are clear then drive your car for atleast 50 mile's without turning the key off. That usually reset's them. Let me know how you make out.
