95 Saturn Sl start but stumbles

Long story short,a few weeks ago I replaced the engine and it ran fine, suddenly it just died on me, I checked the code, and I had to replace the ignition module, after one week later driving uphills it started to lose power, once again I checked the code,This time it was the EGR valve so i replaced it as well, after a week it started stalling more and more,getting progressively worse but now rpm varies between 1500 ( this is the max that I can go)and drops to 800 rpm or less. when I press the gas but If not just around 200 or 800 rpm,I cleaned the fuel injectors,i changed the spark plugs and wires.I cleaned the Throttle body and I found out a lot of carbon build up, I tried to clean it up as much as I could, but it did not solve the problem:disappoin:1zhelp:

Kinda sounds like a plugged cat. Remove the front O2 sensor (it will be loud) and run the engine to see if it improves.

Yeah! :rofl:you was right Cat Fuzz (http://www.automotiveforums.com/vbulletin/member.php?u=115751)http://www.automotiveforums.com/vbulletin/images/icons/icon14.gif, Thanx a lot I did removed the catalytic converter,and a bunch of black dust and small pieces of ceramic came out from the cat(replaced),also I did replaced the O2 sensor,and now when I want to start the car it's kind a hard, I have to press the gas pedal all the way down and start, I did replaced the map sensor and looks like I solved the problem but a couple hours later I tried to start the car, and again, gas pedal all the way down and start. Any suggestions or help will be appreciated

Glad to have helped.

Next thing on the list would be to remove and clean the throttle body. You might want to remove the IAC from the throttle body as well and carefully clean it with carb cleaner. Don't move the plunger on it. Spray with carb cleaner and let it do the work. You might want to gently wipe it a bit. Clean the IAC passage and clean the butterfly valve all around and open it by hand and wipe down the edges.

Bad ECTS causing your engine to flood. Replace it with a brass one. Your car has two ECTS'. Replace the one with the two wire connector.

I did replace the ECTS (Engine Coolant Temperature Sensor), and I removed the Throttle body and I did removed the IAC Sprayed with carb cleaner.:cool: Put everything back together,next step, start the car....and boom!!! has been running like new.http://www.automotiveforums.com/vbulletin/images/icons/icon7.gif
