Ford F-150 - 1997-2003 :: Throwing Code P0171 And P0174?
97 F150 4.6 200xxx on recent rebuild. My truck is throwing P0171 & P0174.
I think I tracked it down to leaky IAC and EGR gasket. I sprayed both with carb cleaner and the RPM's dropped.
My question is, wouldn't the RPM's rise instead of drop? I was under the impression that they would go up if the gaskets were leaking. Or did I use the wrong spray?
Golf IV / Jetta IV :: Misfiring After Valve Cover Gasket Replacement
I did a valve cover gasket replacement. Changed all spark plugs and coilpacks. The car is still misfiring. I also just did the timing belt and water pump. Why it's still misfiring?? I'm new to this whole forum thing so bear with me lol. I'm wondering if it would be my cat, fuel pump, fuel filter. Or could it be a sensor?

I have a 1999 F-150 with the 4.2L engine. I recently did a motor swap as the original motor was bad. I bought this truck as a project truck and have enjoyed working on it.
When I did the engine swap back in May of this year, it took a while to work out all the little bugs and quirps. However, after a while of running the truck it threw a few codes. I replaced a lot of the emission components and no more codes for several months until last month the truck started throwing the infamous P0174 "too lean bank two"... I have replaced the pcv valve and all the hoses to include the little rubber boot under the front of the intake, all 4 O2 sensors, MAF sensor, EGR, DPFE, IAC valve, new wires and plugs to include coil pack, fuel pressure regulator, and all the vacuum lines that are under the hood.
The truck runs fine, has power, but about every couple weeks or so it throws this P0174 code. I know there are alot of threads on here about this problem and I have read many of them. It only throws the P0174 and not the P0171. I am wondering if there could be a problem specific to "bank 2" that I am over looking.

View 1 RepliesPontiac - Leaks - Grandam :: EGR Valve Throwing A Code
I drive a 1995 3.1L V6 Pontiac Grand Am SE.
My mechanic told me that my EGR valve was throwing a code, so I took it off and cleaned it out and tried to fish out some of the carbon in the air intake tube. I used carb cleaner on the valve and the tube and I sprayed a little bit of air duster into the tube, but it made a funny noise so I stopped after about 1 second of spraying.
When I put it back on, I forgot to snap the wiring harness back onto the top EGR solenoid. I reconnected the negative battery cable and started my car. The gauges red fine. I revved my engine a few times and everything seemed okay. Then I turned off my engine and then turned it back on to listen for any rough idling (that's why I decided to clean the EGR in the first place). Then I turned it off.
When I got out of the car, I realized I forgot to reattach the wiring harness to the EGR. I disconnected the negative battery cable and it sparked a tiny bit. I reconnected the wiring harness to the EGR. Afterwards, I noticed that it had leaked some fluid (I'm guess oil?) into my engine. There was a very small amount of light smoke or steam (not sure which), but it stopped a minute or two later. I've attached a picture for reference.
Is it safe to reconnect my negative battery cable and try restarting my car????

A few days ago I noticed some oil leaking from the left (front) valve cover area and I suspect it's the gasket. Fortunately, I didn't see any leaks from the back cover. It seemed like an easy job to replace the gasket, but as I started to disconnect the wiring, e.g., cam sensor, spark plugs, etc., I can't seem to find a way to remove the black plastic wiring harness 'housing' out of the way.

I have an 2008 Mercury Sable Premiere with a 148 miles on it. Just got the Valve Cover gasket replaced and new water pump put on. The car is running very smooth as it always done,but now when coming to a stop,it either acts like it wants to cut off or sometimes it just shuts off. When it cuts off I immediately crank it back up and it starts, but why or what could be the problem? It also starts up a little slower than before and I know its not the battery because that's brand new.
View 6 RepliesPassat (B5) :: Oil Loss After Cam Tensioner And Valve Cover Gasket Replacement
I noticed the oil smell that can be associated with a leaking Cam Tensioner Adjustor Seal from my 2003 1.8T Passat a few months ago. The dealer confirmed that it was leaking and that it was covered by my extended warranty since my car was 5 years old and at 70K miles. I had the work done and after I picked up the car I noticed that the oil level was at the top of the hashes not at the top bend like it was when I took it in.
I don't know what caused it to drop to the hashes but I do know that the level has dropped to 3 visible hashes in the little over 1K that has been put on the car since then. I am concerned because in it's first 70K miles the car did not visibly lose a drop of oil.
Any logical cause for this annoying trend, the only thing that changed was that the Cam Tensioner and Valve Cover Gaskets were replaced. Is it possible something else was messed up during the repair?
Ford F-150 (2004-2008) :: PCV Replacement Without Taking Off The Valve Cover?
5.4L 3v engine: The PCV is located in the drivers side valve cover. Tried to pull it out with no success and came to the conclusion that maybe it's threaded and a nut locks it in from the underside of the valve cover. Can this thing be replaced without taking off the valve cover?
View 4 RepliesPrius (2004-09) :: Check Engine Light Throwing Code P1121 For Coolant Flow Valve
My check engine light was throwing the code P1121 for the coolant flow valve. Toyota replaced it under a warranty enhancement (I have 134k on it), and since then my mpgs have gone from 46 to 50.
My AC is working much better now, too. My theory is that the valve can be in a semi-failure mode for a long time before throwing a code. Now that My coolant is flowing the way that it should, heat is being dissipated more efficiently.
Mazda :: 2004 - Idle Bounce While Coasting After Valve Cover Gasket Replacement
I've got a 2004 Mazda 6 with the 3.0L V6 & a 5-speed, with about 128k miles.
The car runs fine, but was leaking oil onto the exhaust manifold and so I recently had the valve cover gaskets replaced. the mechanic could not get replacement gaskets from Mazda, and so changed the valve covers themselves also, and consequently needed to replace a couple of hoses that connect to the valve covers.
Since the repair, the car drives fine - acceleration seems normal, I don't notice any performance issues. The CEL is NOT lit.
1) When the car is in neutral, but rolling, the idle consistently bounces back and forth precisely between 1250 & 1500 rpm. This occurs always, and happens whether the gearshift is in neutral or the clutch is depressed. With the radio off I can hear the engine surging when this is going on. As soon as the car comes to a complete stop, the idle immediately drops to the a rock-steady position just below 1000 rpm, as it always has.
2) I assume related to the above, but since the repair my gas mileage has dropped from its usual 18-19mpg to 15.7-15.9mpg as recorded at two fill-ups, and my current tankful is looking to return equally low mileage.
I brought the car back to the shop and the mechanic took the car out for a drive with me, with his computer hooked up while we drove. He found nothing wrong, nothing out of whack, and saw no evidence of any air leaks.
1) Seems strange to me that the valve cover gasket couldn't be obtained, and new valve covers were needed. I want to believe the garage is being straight with me. Is this really plausible?
2) What could cause the idle to behave this way? I understand what a valve cover does (in my earlier years I changed the cylinder head on my old Saturn) and can't figure out how or why changing the valve covers would have an effect like this.
That leads me to conclude this is more likely caused by the new, slightly different hoses attached to the valve cover, but I don't know exactly what those hoses do or why they connect to the valve covers, so I'm stuck here.
Ford Fuel System :: 1982 Truck - 2150 Power Valve Cover Replacement
Well I have a 2150 carb on my '82 truck, I looked in my parts and illustration guide and found what should be a fairly close overhaul kit for my truck based off it being a non high altitude truck and it has A/C and its a 302 with C6 transmission 2 wheel drive.
Down side is the power valve that came with my kit is a two stage power valve and I currently have a single stage power valve.
If I were to use this two stage power valve where would I buy a replacement two stage power valve cover?
Ive been looking but cant find any anywhere and I am to the point of figuring out what power valve my truck has currently so I don't have to put my only vehicle down for multiple days for a simple carb rebuild.

I have a 2002 F250 5.4with Air Conditioning. The valve covers are leaking and the gaskets need to be replaced. I am attempting the valve cover gaskets. I was able to get the drivers side cover off with some difficulty. For the passenger side valve cover. There is very little " no" room to get at the bolts. I read somewhere that I may have to drop the engine on that side. I will do that if I have to.
