Idles rough/Changed ECTS

Clean out the idle air control valve and see what happens

where is that located? and does the cpu have to be reset in order for the engine to read the new sensor?

also when i got the car it had water in the spark plugs due to the person cleaning it. I soaked up all the water i believe...Could this also be the problem and make it idle rough and hesitate then accelerating

Could mean a blown headgasket, cracked head or block-Yes it will cause your problem-is it overheating?

no not over heating at all and does not leak antifreeze at all.

Have it block and pressure tested to find out why water is in the cylinders

if the block was craked or head gasket blown would it leak fluid? The car engnie was washed with a high pressure washer which is what im guessing did it not sure...

You need to have it tested and then comeback with the testing results

Just to add to this if the water was in the spark plug well that the plug wires sit in and not the cylinder itself washing the engine will fill those wells up with water really common on those cars the plugs sit down in a well empty cavity a good 3 inches.When i worked at the saturn dealer the wash guys used to fill the plug wells up with water all the time and make me look bad.Because the car would run real bad when the customer drove off.So i would inspect the plugs themselves clean all that water out.Also pull the plug wires off the coil towers see if the towers are all corroded thats very common on that car for the coil towers to get corroded.Also did you change the top coolant temp sensor with one wire or the bottom one with two wires going to it.Did you inspect the connector to the coolant temp sensor they get corroded also real common.If the terminals to the coolant temp sensor connector are green or blue its corroded and needs to be replaced.Have you checked for codes yet?

I replaced the bottom one with 2 wires. I checked the plug and seemed fine, i havent yet checked the plugs yet again but will tonight and also check the coils. tonight as well...Thank you very much for the response to that. Havent checked for codes since the check engine light is not on. Would it still read codes of it is not on. Also would reseting the CPU help?

You replaced the correct coolant temp sensor but make sure the inside of the connector isnt blue or green.Do you know how to get the codes out of your car by flashing the codes out of the service engine soon light?

No, i didnt think you could get codes if the service engine light was not on.... it didnt look blue or green when i changed it and since i have changed it the coolant light has not came on. When i first got the car i thought i got all the water out of the spark plug wells but i may not have gotten it all out. what is the best way to do that? just soaking it up with a paper towel or ??? your help is greatly appreciated

Even if the light isnt on you can still get codes out of the computer you could have codes stored in the computer.

o ok, i didnt realize that. How do you do that ?

Also would water in the plug wells make ir idle really low and bounce from 800-900 to 600-700 and then back up to 800-900 and feel like it wants to stall out when sitting at a stop light.

As far as the water goes i put a rag over the hole and blow the water out with my air compressor.But i guess you could use rags or paper towels.

Water in those plug holes makes it run real bad because the spark is getting shorted out instead of firing the plug.

I kinda thought that but wasnt sure and everything i have read points to the ECTS or IAC Valve sensor or EGR valve id just hate to keep putting money into even tho its not much to get it running like its supposed to. It rean fine for 2 days after i initially got the water out then it started to run rough and hesitate when accelerating, i thought i got all the water out bt maybe there is a little left in there. Im going to check the IAC valve to see if its dirty as well

I posted how to retrive codes by flashing your service engine soon light.If the low coolant light starts flashing while retriving codes get those codes also those would transmission codes.

is this autozone could do cause i dont have the gadgets to do this my self

See if there is codes if the egr is sticking it will set a code.Look in the plug holes with a flashlight to see if there is water in there.Also check the plugs and coil towers you might need a set of plugs and wire's.Also make sure your car doesn't have platnuim plugs in it they carbon foul in those cars and will cause miss fires.Let me know what you find.

awesome thank you ill let you know tomorrow. I just realized youw ere the one i was talking with the other day, i will let you know tomorrow as soon as i can after i check tonight. thank you

Keep me posted.

so i took out the spark plugs lastnight and inside the wells was a rusty colored liquid that almost looked like oil. I actually tasted it to see if it was oil as i used to work for an oil distributor and have had my fair share of oil splash on me. it didnt taste like oil and the tips of the plugs were rusty. I purchased some new plugs but havent had the chance of changing them yet. I wiped the wells with a paper towel to dry them out and will be changing the plugs later today. Do you think the usty pulg tips could cause this problem?

Yes it could cause that dont forget about the wires being corroded and the coil towers.I hope you just got some stock ngk plugs they run the best.keep me posted.

yea i didnt get anything special and no platinum tips. It was pretty late when i checked th plugs and couldnt really see the coil towers but will be checking the coil towers this afternoon. I will let you know what happens. Your help is appreciated.

Thank you

Also check the plug wire ends where they go onto the plugs make sure there is no rust there.The plugs get gaped at. 040" keep me posted.

awesome thank you

I changed the sprak plugs as the tips were rsuty i changed to plug wires cause the ends looked about burnt out and the coil towers were corroded. I Cleaned the towers off but am buying a new coil, the car runs completely fine now and has no problems ideling or anything thank you for your help.... i really appreciate it

your welcome glad to hear it if the towers were badly corroded best to replace the coils themselves at that point.

they were bad ebnough to have replaced it but i just cleaned them off with a piece of steel wool and getting the coil this week...

What i have seen is if there bad enough after cleaning the wires wont stay on the coil.Did you put dielectric grease at each end of the plug wires?If not you need to do that.Also did you ever check and see if you had any codes?

no codes and the wires had the grease on them

Alright i always like to put a little more then comes with the wires just to be on the safe side.

ok sounds good thank you

Your welcome hit me up if you have anymore questions

will do
