I have a 92 4 cylinder dual over head cam 4 speed. It''s a coup, not sure if cl sl or what lol. I am having troubles starting my car after work. It starts fine in the mornings but when I get in after work it has troubles starting. I do the regular, clutch gas and ignite. It turns over and acts like it''s hitting but then it just turns over and hits when i pump the gas. I can smell the gas and everything, just not sure whats wrong. Any help?

I would replace the Engine Coolant Temperature Sensor and its associated connector at the first opportunity ...

The engine coolant temp sensor is the one on the resevior? I''m new to the saturn world as it''s obvious. I figured I''d take the EGR valve off and give it a good cleaning and give it a tune up, I will try that sensor you''re talking about. Thank ya muchly!

No the ECTS is a two wire sensor located in the cylinder head (driver''s side). Squeeze the connector to remove it. Replace sensor with brass style replacement.

Derf has the exact sensor pinpointed ... thank you

Just re-read your post.

Addl tip: Don''t hit the gasyou''re probably flooding it.
Clear the flooding by holding the pedal to the floor for five seconds while cranking. Then start without foot on the gas.

Still need to change the ECTS.

I found the plug you''re talking about a while back but had no clue where it was to be plugged in at lol. I feel like such a dork! Do sohc have one on them? If they do I''ll go to the yard by my house and grab one and just get a new sensor. Thank you lots guys, I''ll go and do it a.s.ap!

Answered your other post. The IAT and ECTS are identical to each other (as far as temp sensors go) but they mount in different places and monitor temps of different things.

The IAT mounts in the air intake tube and monitors incoming air temp (see other post); the ECTS mounts in the cylinder head and monitors coolant temp.

Yes the SOHC''s have them.Edited by: derf
