The check engine light came on and has not gone off, the car idles and stalls almost completely when stopped at intersection(red light), the engine mounts were replaced two years ago. I read about Ford SPI engine dropped valve seat-problem starting at about 70,000. Can you please tell me how what type of specialty shop is best to diagnose this problem? If it is the dropped valve-seat problem and the top end the valve seats come loose from the cylinder head and drop into the cylinder and if it is in little chunks then they sometimes they can blow out your exhaust pipe and be okay and you just kind of it smokes and you have the cylinder head replaced. What type of shop would be best to get the cylinder head replace. I read you can get the reconditioned heads from eBay or is it better to get from salvage yard? What type of machine shop would service machine shop cylinder head valve job? Is it better to get another engine that to have the cylinder had valve job done? I noticed smoke from exhaust but I did not connect how it may have been related to this. I am on limited funds.

First thing is to quit believing every thin you read a lot of these people are quacks. Then go to an auto parts and get it scanned for codes they do it for free then get back with the code to us do not have auto parts sell you any parts. If you drop a valve seat you can pretty much kiss the engine goodbye, but get us the code first. If it is a misfire code then go see a mechanic misfire codes are 0300-0304 because it can be anything. But if not get us the code.

Is this a natural gas powered car? If not these are what to look for in picture. If it is an O2 sensor number one is before converter two after converter. See picture.

Hello,
my 2003 focus lx 2.0L L4 SOHC 18,000 miles has had the engine light so I went to autozone to read the code.
Autozone obd2 printout says "P2195 lack of heated oxygen sensor- Bank 1 Sensor 1 HO2S11 switch- sensor indicates lean"
they said "Your car is burning more fuel. It's a common problem. It's usually the 1st sensor to go out. It's possibe to DIY. It looks like a spark plug in the exhaust pipe b4 the catalytic converter by exhaust manifold."
I checked with Herko Automotive Group and they said "For your car 2003 FORD FOCUS 2.0L L4 SOHC in the position sensor 1 (Upstream) you need the oxygen sensor number SG1813."
1. I think I see whee the bank 1 sensor 1 in front of the engine but can someone post a pic highlighting the location
2. How reliable is this advice from autozone & herko? Should I just replace the sensor or what's the next likeliest fix for this?

Hello,

Ok, there are a few things that can cause the code you are getting.

40) For Continuous Memory Only DTCs P1130, P1150, & For KOER & Continuous Memory DTCs P1131, P1132, P1151, P1152, P2195, P2196, P2197 Or P2198: Upstream HO2S Not SwitchingContinuous Memory DTCs P1130 and P1150 indicate when an HO2S fails to switch due to a circuit or fuel at or exceeding a calibrated limit. KOER and Continuous Memory DTCs P1131, P1132, P1151, P1152, P2195, P2196, P2197 and P2198 indicate a concern when fuel control system does not detect HO2S switching for a calibrated time. DTCs P1130, P1131, P1132, P2195 and P2196 refer to HO2S-11. DTCs P1150, P1151, P1152, P2197 and P2198 refer to HO2S-21. Possible causes for these faults are:

Fuel System - Excessive fuel pressure, leaking or contaminated fuel injectors, leaking fuel pressure regulator, low fuel pressure or engine running out of fuel or vapory recovery system fault.

Induction System - Air leaks after MAF sensor, vacuum leaks, PCV system or improperly seated engine oil dipstick.

EGR System - Leaking gasket, stuck EGR valve or leaking diaphragm or EVR.

Engine Mechanical - Engine oil overfilled, cam timing, cylinder compression or exhaust leaks before or near HO2S.

Also, I would check for a burnt fuse, since the O2 Sensor is Heated it requires a fuse.

As far as the Advise from AutoZone - they are only reading what the Code Def is and not what other conditions can cause the code and they would love to sell you an O2 Sensor that you may or may not need.

As for the Herko Automotive Group I honestly haven't heard of them, so cannot say.

The only way someone can help you on this website is if you tell us what the trouble code(s) is/are.
Go to an autopart store like autozone; they can scan your car and retrieve the trouble code(s) for free.
Once you have the code(s), post back with them and we'll start from there.

Ignition System
Faulty Evaporative Emission System
EGR &/Or PCV System
Air Intake System
Engine Oil Contamination
Fuel System
Exhaust System Leaks Or Restriction
Engine Cooling System
check all that first including checking air intake for holes and check O2 sensor for a broken wire.

Went to the dealership, was told that it was the imrc actuator, I took apart what I believed is the vac actuator, I wanted to know if this is the correct piece. I also wanted to know if there is a small test I can preform on the actuator while it's out the car to see if it is indeed the correct piece.

More information: I have two imrc solenoid on top of the intake. And followed the one of the right to get the the actuator that I pulled out. I assumed that this is the bank 1, the bank that is giving me the code p2004. Did I pull out the right one for bank 1 or is it the other "actuator" that is connected to the solenoid on the right side that is giving me the cel. I'll include pictures.

If I was indeed right the whole time can someone direct me to where I can buy a new actuator.

Alil hard to see but that's the spot where I took the piece from you can see the vac line there. What looks like the other solenoid is connected too is that grayish piece in the middle (the second actuator?)

Why are you so confident that component is the cause of the code? There are 22 pages of tests to resolve that code.

Hi amckey,Welcome to 2carpros and Ty for the donation.

Start by checking the spark plug,compression and fuel injector on #2 cylinder.

The mechanic told me it was under the throttle body, on the right side of the intake, which vac lines in it. So that's where I looked and found. I also followed the right solenoid to get to that piece. So I'm like 80% sure. That's why I'm here. For the other 20%.
