Well it sounds like a blow head gasket does the oil look like a milkshake yet? if not than the crack is very small just enough to start troughing codes need to get a pressure tester and see if there a leak you can rent the tool at any auto parts store. good luck LARRY B
Thx for reply. I did oil filter change 3 days back with egr valve replacement. Yes mech applied sealant on head gasket and tighten the manifold. I got codes after 2 days running.
sounds like you need to have a better scan tool hooked to you car it will give you a lot more info and pinpoint the problem.

SOURCE: service engine soon light keeps coming on. Now low coolant light
I would start by doing an oil change myself so you can examine the oil and look for water/antifreeze in it. You will be able to see it separate from the oil and you can smell the antifreeze. If there is then you have a leak between the water jacket and the heads somewhere. More than likely the LOWER intake gasket is leaking into the head. You said they replaced a gasket but was it the UPPER or LOWER? If it was the LOWER did they use RTV in the correct areas? Did they torque the intake bolts to the correct pressure and install the bolts correctly? I know you don't have these answers but these could all be part of the problem. It may be leaking more at #2 cylinder and causing it to foul more than the others. Also just because a mech pressurized the coolant system and didnt see any change in pressure (hopefully he wasn't just looking for visible leaks) the issue may not happen until the engine is hot, as metals behave differently when heated, especially aluminum which the LOWER intake is made. Have a mechanic or mechanically inclined friend (gearhead) remove the #2 plug wire, then kick the engine a few times without starting it, enough to let any fluid get into the chamber, this would include gas btw. Then remove the plug and look for any wet residue on the plug, gas will evap. quickly, antifreeze/oil won't. again try to smell the residue and if necessary, lightly touch some to your tongue, antifreeze has a sugary sweet taste that is easily detectable. Remember any time you are working with chemicals such as waste oil and especially anti freeze, minimize spills and clean them up quickly and completely and place the spent fluid in a sealable container and take them to a collection center for disposal. Waste oil is a carcinagin (cancer causing) agent and antifreeze (glycol) new or old will kill any animal (child, dog, cat,etc) that ingests it. Many auto parts stores and some other retailers that sell oil and antifreeze will take your wastes if you bought the replacement fluid from them, check before you buy.
SOURCE: Engine will not idle, stalls at stop lights etc - EGR code
To me if the engine will not idel and stall once you have stopped, that points to an IAC (Idle Air Control sensor) which is located on your throttle body. The part is very easy to get to and changes out pretty quickly. Hope this helps. Thanks for an honest rating and for using FixYa!
SOURCE: EGR Valve, O2 Sensor
Absolutely a bad o2 sensor can cause problems with performance. If you replace one it is highly recommended to replace both or all four depending on your vehicle. If one o2 sensor is making your vehicle run rich you will burn more fuel and in return increase the amount of carbon or unburnt fuel if you will in your egr valve you could probably get away with cleaning it but I would recommend replacing it, it will save you from having to pull it off again. Check your catyletic converter because long exposure to carbon will mess it up.

Doubt it's the exhaust. Does it run rough or just idle so low it quits

So the latest update is here..
Today o2 codes p0133 and p0153 appear again after clearing 2 days before though no indication of coolant leak or low so far.
Still i am figuring out the issue but everything looks normal.
Suggestions pls.
