2006 Subaru B9 Tribeca, 160,000 miles. Misfire throws check-engine light twice daily, compression leak, getting worse. Valve job? or trade?
View 7 RepliesOur beloved 2004 Subaru Forester has the check engine light on. We've been told that the 4th cylinder has either low or no compression. Is this fixable/worth fixing? Would you replace the engine? The car has 183K miles on it, and runs great! It is stuttering now, due to this issue, but otherwise - runs great and is in good condition!

View 3 RepliesThis is my friend's car and I have never looked under a Subaru hood before. She is getting an intermittent check engine light with codes for cylinder misfires on one and three. Today, I inspected the plugs and all four looked identical, a nice uniform tan color and good condition. No sign of deposits or oil. Did a compression test and found the driver's side bank at 155/150 and the passenger side bank at 185/190. My question at this point is which side is cylinders 1 and 3? The front-most cylinder is on the passenger side. Is this the number 1 and 3? If so, then the low compression on the other bank cannot account for the misfire.
View 5 RepliesI have a 2005 Toyota 4Runner. 355,000 miles. No problems with it until now. About 2 weeks ago Check Engine Light came on. I replaced spark plugs (they were due), checked coils and fuel injectors and still have Check Engine Light on with code P0301 (Cylinder #1 missfire).So compression tests were done and cylinder #1 had 120 psi and others 170. I suppose 120 isn't terribly bad but is significantly lower than 170.
Question 1: If I reset the check engine light (turn it off), do you think it will pass California smog test?
Question 2: What do I need to cure the problem? Engine rebuild? JDM? or retire the truck?
When I had a new battery installed, the check engine light came on; initially, testing showed 2 valves performing "intermittently". Have done a full tune-up with new spark plugs & rotor, which briefly fixed it. Anything that can be done other than a full valve job?
View 7 RepliesAbout a week ago I was driving my Pontiac 2003 Grand Am V6 and it began to violently shake and the "check engine light" came on and started blinking. I then immediately took it to the mechanic It has been with the mechanic for 6 days and they were unable to locate the problem. They called me today and I was told that I have no compression in one of the cylinders (I have done business with them before and felt comfortable in that I wasn't being taken advantage of). Also, is there any problems in the future with getting a cylinder replaced i.e. other parts of the engine that might correlate?

View 3 RepliesI have a 2003 f250 5.4 with a couple of bad valves and low compression and a dead miss because of it... I just bought what appears to be a 2001 5.4 from an f150... I am worried now this engine wont work and cannot find anything online that can tell me yes or no....
View 12 RepliesWith vehicle engines in the past, I have used a compression check as a fundamental part of routinely checking the wear on an ICE. My usual method was disconnecting the ignition, removing spark plugs, inserting the compression gauge line in a spark plug hole, and turning over the engine with the starter. How exactly do I do that sequence with a Gen 3 Prius?
If that method is not feasible, would a "leak down" method of checking compression such as we did on old aircraft engines possibly work with the Prius ICE? To do that I would have to be able to carefully position the crankshaft so that the intake and exhaust valves were fully closed on each cylinder in turn. What is the safe method to do that with the Prius ICE?
Exactly what the compression reading should be? I am assuming that if the engine is spun at 1000 rpm by MG1, the correct reading would be 13 to 1 or 13.5 to 1. Or?
I've got a 2006 B9 with about 64,000 miles. Just a bit ago my check engine and ABS light came on, along with my cruise light flashing.
After researching a little bit on the forums and couldn't find an answer, I took it into the dealer, to which I was told that there was a bad oil pressure sensor for the right-hand side of the motor. I had them replace it out, and less than 20 miles down the road, the same lights appeared on my instrument cluster, and I took it back to the dealer. They informed me that there was now a bad sensor on the left hand side that would be another $380. I scheduled an appointment for later next week, and had them reset the error.
On the same day, about 2 hours later the lights reappeared on my dash, and I took the car over to a local parts store, where I used their scanner and the car now spit the following errors:
Camshaft position actuator A - Bank 1 timing over advan.
Camshaft position actuator A - Bank 2 timing over advan
Cam/crankshaft pos. correlation sensor A - Bank 2
Cam/crankshaft pos. Correlation sensor A - Bank 1
Camshaft position actuator A bank 1 timing over - advan
Camshaft position adctuator A bank 2 timing over -advan
Cam/crankshaft pos correlation sensor A - bank 1
I reset the codes, and waited another day for the lights to reappear on the dash. Again, I rescanned the errors, and found the same top 5 codes that I listed above.
Is there something more major going on here with the computer?
Had an issue with "check" engine light turning on and "cruise" control light flashing, intermittently. Dealer said we had dirty oil contaminating some solenoid valves in the system but we had just done an oil change and do so every 3-5K (car has 170K). They recommended switching around the sensors and doing an "oil flush" with another oil change. The warning light problem hasn't recurred, in the past month, since we started giving the gas cap a few extra turns after a fill-up. We're getting ready to buy a new car and don't want to give what might be a serious problem over to the next owner.
View 6 RepliesI have a 2007 L.L. Bean Edition Forester. The cruise light is flashing and check engine light is solid. I am well into my retirement age and nearest dealer is about 2 hours away. Is this something that local mechanic can fix? He is very good, but not Subaru schooled. I'm afraid to drive it now.
View 2 RepliesThe problem that causes the check engine light to come on cannot be traced. The diagnosis is multi engine misfire. The dealer has checked and recheckedbut problem still exists. The last time my mechanic changed spark plugs he noticed oil on one of the plugs he removed in the rear side of the engine. He replaced the plug with the rest of them. Could it be that one or more of the spark plugs are sucking oil and causes the misfire? If so what could be the cause of that. Do I need a full tuneup? My dealer recommends replacing the cam shaft pulley because it's loose and this may or may not solve the problem. I'm not a mechanic but it appears as if the problem has something to do with the spark plugs sucking oil since the check engine light might go ou for a week or so and then come back on for a while. Lastly is it dangerous to keep driving the car especially on long trips?
View 1 RepliesWhat are reason for the check engine light to come on and off and when a different person drives it. When it comes on? I guess I am looking for other opinions when I drive it I drive it respectfully but the owner bit of a speed lover.
View 14 RepliesGeneral misfire when the engine light comes on. This error has been occurring almost daily, sometimes it pins it down to cylinder 3. My wife's nephew who is a mechanic says it could be the sensor, but I have only been getting around 30 mpg though the car seems to run alright. I did go ahead and get the plugs replaced, as I was told it could be a bad plug but the error light still comes on as before and the mileage appears no better. What could this be? I am retired on fixed income and dread the very idea of an expensive diagnostic & repair session with a dealer service. Their solution for about everything wrong has been to replace the gas tank (three times already in the life of the car). Last time that did not fix what was going on with the car..
View 10 RepliesI bought my Subaru in 2004 with 14,000 miles on it. The check engine light began coming on soon thereafter. The Subaru dealer has replaced my catalytic converter (the so-called problem) -- 3 TIMES up to 85,000 miles. The check engine has continued to come on and it goes off since then. Mostly, it's on, but now and then, it goes off. I bought my own diagnostics kit because I got tired of taking it in every time the light came on. I'm told it's the usual problems plus they usually have me get the oxygen sensor repaired. I've also been told to make sure my gas cap is tightly closed. Still the check engine light continues to come on and now and then it goes off (it's currently "on").
View 4 RepliesEngine light came on two weeks ago. Had the code read at Advance Auto Parts. Code = P0420. The only performance issue was that it stalled when I started it the other day for the first time since I bought it last fall. Are there any other clues to tell what it could mean (catalytic converter vs. 02 sensor vs. anything else)? Is it really worth trying some kind of catalytic converter cleaner product?
View 1 RepliesI'll try to break this down as best I can. I went to my mechanic this am with a check engine light. My suspicion is 02 sensors. This was confirmed as a problem area, but separate they said I had a spuratic misfire in cylinder 4. With that info, i pulled the plug to inspect (I had just installed new ngks in it and they have 18,000K on em.
I put beldon wires on about 8k ago.) plug looked to be normal, but there was definitely a puddle of oil from the valve cover leaking. Oil went into the cylinder head but I didn't really think that was an issue. Nothing abnormal jumped out at me so I reinstalled plug and checked all wire connections at both ends and called it a day.
Then I drove it. Check engine light flashing. Major performance stutters, etc. I drove it for about 20 miles and hoped it was just the oil raising hell in there and it would burn off eventually. It hasn't gone away yet. Maybe coil pack. Can the single portions of that pack be replaced, all i see them sell is the full three as a unit.
I just received a check engine light and the diagnostics from dealer were that a misfire was detected for cylinder 1 , 2 , 3 and 6 .
What needs to be changed? and mechanic said maybe the complete coil pack and wiring . Although, the code was reset and i haven't had the CEL come on prob in a week now , so i guess no other misfire has happened.
So, my check engine light has been on for months. I knew that I needed a new oxygen sensor (block 1-pre-cat), so I replaced it today after the car began to sputter and misfire. Well, I thought that would fix the problem, but it hasn't. Some of the hesitation is gone, but the sputtering is still very bad. I'm going to replace the spark plugs tomorrow and see if that works. I was also told to clean out the catalytic converter, but I don't know how to take it off. It wouldn't hurt to just bang out all the debris. Any DIY on taking off a catalytic converter for a 2000 VW Golf GTI 1.8T?
