Prius (2004-09) :: Vehicle Low On Fuel Causing ECU To Shut Down Fuel Injectors
I took my 2008 Prius to Jiffy Lube to have oil changed. When driving away, I made it about one block and all warning lights came on: Master Warning, Hybrid System Warning, Brake System Warning, Malfunction, etc. I pulled the car over and stopped. I started the car again, lights still there - drove 2 blocks back to Jiffy Lube and lost momentum about one block away, with pedal to floor, I could drive about 5 miles an hour into the bay. They looked at it for about 30 minutes and claimed I had bird seed that dropped under the air filter.... I said "goodbye" called AAA and had it towed to my dealer. They said it was because air had entered the system due to my being low on fuel. I have never heard of being low on fuel and it causing the car to shut down nor did I ever get a warning of low gas, still on one bar. Each time I restarted the car at Jiffy Lube, it started fine, drove forward or backward, then lost momentum again. Still no warning of being out of gas. The ticket from the dealer states:
"Vehicle low on fuel causing ECU to shut down fuel injectors when engine started to misfire. Found codes P0A0F, P3190 in system. Added 5 gallons of fuel and reset ECU."
Ford Fuel System :: 1988 - Got Code 41 - Lean Miss At Idle - ECM Or Injectors?
1988 F250 351 5.8
I've worked for months on this truck and I now have it in the shop. The truck shows a 41 code and has a lean miss at idle that get worse during acceleration and cruise. The injectors were refurbished 6 months ago and the ECM was replaced 3 months ago. All sensors are new and within specs. Fuel pressure is good and there are no vacuum leaks.
The mechanic has verified that the condition is not electrical related. The O2 sensor will react if carb cleaner is sprayed into the throttle but other wise shows constantly lean. He's now checking all pins at the computer for any off condition. He is suspicious of the refurbished injectors. I'm wondering if the computer somehow went out again. Which way to go or what/how next to test?
Prius (2004-09) Fuel :: 2008 - Sudden Drop In Fuel Economy - Water Leak?
I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).

My 2004 Ford Freestar SEL (the 4.2L version, 123,000 miles) is missing. The computer code is P0302 which, from what I can find, indicates a misfire in cylinder 2. I had this same code at 99,000 miles and ended up having the spark plugs and wires replaced around 100K miles. It was all running fine until about a month ago and started misfiring again, badly. I thought it was related to the rain but it is doing it all the time now. At times it gets so bad, I have no power and the computer disengages my A/C (bad at this time of the year). I tried a running a fuel system cleaner that specifically mentioned cleaning the injectors, hoping the problem was simply a clogged injector, to no avail (I know I probably wasted my $10 here). I have a couple of questions:
1. Am I doing damage to the engine or transmission by continuing to drive it? I really don't have a choice but need to know how urgent it is.
2. Does this thing have a traditional distributor cap & rotor or is there an electronic ignition module the plug wires connect to?
3. Where would I find the illusive distributor or ignition module, in theory?
4. Any other theories as to the cause of the misfire (cheapest first)?
Prius (2001-03) :: Check Engine Light - Replace 4 Fuel Injectors And Clean Throttle Body
I brought my Prius, 128,000 miles, into the dealer with the check engine light on. Runs fine, and checked the gas cap. Toyota dealer said they need to replace 4 fuel injectors, replace oxygen sensor, and clean the throttle body. Check engine light needs to be off so I can pass emission test.

This has been an ongoing issue with our 2006. We purchased the car about a year ago and have put on just over 8,000 miles. Rebuilt the battery pack and replaced the 12v battery. This is my wife's car and I have a 2005, so I have done some diagnostics, tuneup, and even swapped some parts between the two cars trying to narrow down the issues.
Only recently have codes been recorded. The car is has a noticeable misfire at low RPM. Here is what has happened up until now:
11/29/15 - replaced spark plugs - #1 was fouled so I swapped coils between cylinders 1 and 4
2/25/16 - replaced 12v battery with new battery
4/1/16 - P0300, P0301 codes were first recorded and reset to see if they came back
4/10/16 - swapped Integration Relay with my 2005 (part # 82641-47010). My 2005 ran poorly after the swap, so I put a used one in my 2005.
Gmc - Sierra1500 :: 1989 V8 Will Not Start / Fuel Injectors Don't Spray Fuel Into Combustion Chambers
I have a 1989 GMC suburban V8 350 5.7l that will not start. I have replace the following fuel pump and sending unit, fuel pump relay, ECM computer brand new, new fuel filter. When I go to start it the fuel injectors dont spray fuel into the combustion chambers verified fuel injectors still work by bypassing them and they spray fuel. Fuse's are not blown. I have been told the oil pressure switch might be bad but I'm at my end of sanity on this.
Additional Details : Tried spraying fuel into the throttle body and still no fire, ignition module and ignition coil where replaced 15,000miles ago.
Ford Fuel System :: 2001 F150 - Truck Will Not Turn Over / No Fuel From Injectors
I've got a 01 f150 yesterday stopped running (like it ran out of gas). Has half a tank. Fuel pressure at rails good but truck will not turn over. Fuel pump and filter less than year old.
View 1 RepliesPrius (2004-09) :: 2006 - Check Engine Light - P0420 Code / Air Leak In Exhaust
So today my CEL came on. I immediately looked at my mileage and I was EXACTLY at 500m past my oil change the other day. I checked the dip stick and lo and behold, it was about 3/4" past the full marker. I took it back to the oil change place and had them drain it down to a good level.
I had driven from NH to NY this week. I filled up my gas tank on my way home from NY. Gas cap was on nice and tight for sure.
The code is still on (not sure how many miles or drive cycles is required) for something to clear. I figured it was perhaps due to too much oil added. I decided a few hours later to take it to AutoZone and grab the diagnostic code. It's a P0420 code (Cat System efficiency below threshold: Air leak in exhaust before rear HO2S, AF Sensor Error, Fuel System Fault, Faulty Catalytic Converter).
Prius (2004-09) :: Check Engine Light Code P1118 / Control Fuel Air Metering
I recently had someone run a scan on my 2008 prius, which just had a check engine light pop up on it.
It came back with the following code: P1118 MANF. CONTROL FUEL AIR METERING
Golf/GTI VI :: Misfiring - Code P0300 And P0302
I have a 2011 GTI (purchased new in 2010) with a stage 1 APR tune and a carbonio stage 1 intake. 71K miles on the car, tune has been on it from nearly the beginning, no issues. I have religiously filled with 93 octane gas -- like, always. The other day I was filling up an empty tank in NJ -- land of mandatory attendants -- and I accidentally said "premium" instead of "super." (I normally self-serve in PA). Before I realized what had happened, I had a full tank of 91 in the car.
I run the 93 octane program on my APR, and I couldn't remember how to switch, so I've been running around the last few days that way, seemingly with no issues. I'm not even sure what's supposed to happen if you burn 91 while in the 93 program.
Anyway, yesterday I happened to go full-throttle in 1st or 2nd gear, and I ran into a little stumble. Strange, but I figured maybe this was the result of my refueling mistake. So, I got out my APR manual and figured out how to switch programs down to the 91 program, which I then did. Took the car out again, and was still able to get it to stumble, eventually with a blinking, then solid CEL. A quick VCDS check showed a "Random/Multiple Cylinder Misfire Detected" -- P0300 and "Cylinder 2 Misfire Detected - MIL" -- P0302.
Now at 71K miles, I've never replaced the coils or the plugs, although I have had 2 intake manifolds replaced under warranty. I'm kind of figuring the octane and tune are not really causing this and it's probably just in need of some coils/plugs. what is "supposed" to happen if you run 91 octane on the 93 program? I haven't tired backing down to stock yet, but I could certainly do that and see what happens.
Golf IV / Jetta IV :: Pulled Over Code P0302 For Misfire
I have a 2005 Jetta 2.0 BEV GLS. I got a code P0302 for misfire on cylinder 2. I am pretty sure it's the Ignition coil. I live in Canada and my autoparts store only has BWD brand. I have read this is a crappy brand.

2009 Accent, 1.6L 154,xxx Cylinder two misfire. Engine was rebuilt due to timing belt. Twice. Second time I did it. Replaced plugs, coil packs, all gaskets, (everything new in the head) did a smoke test, compression test 180 psi across all four, used a noid light for coil packs (good) did it at the injectors 1,3,4 did good, but 2 came on then went off. Check resistance and it shows good, replaced injector anyway and the connecter. Still doesn't work. Checked powers and grounds at the rail, good. Good solid voltage. I hooked up a scan tool and tried to shut injector 2 off, no change in RPM or vibration. Scan tool worked for 1,3,4. Used another PCM, still misfire in two. Even jumped a wire from PCM control and 15A inj fuse for the 12V constant (bypassed the harness) and still doesn't work. Also have knock sensor code, just two codes.
View 14 RepliesWindstar :: 1997 GL 3.8L - Intermittent Misfire On 2 / Code Reads P0302
I have a new (to me) '97 Windstar with 128K +. C.E.L. is on and intermittently flashing. The code reads P0302 (Cylinder 2 Mis-fire). No other codes are set. Have cleared them many times and gone through multiple drive cycles.
Description of issue: After clearing the codes, and indeed upon each startup, the car starts and idles smoothly without hesitation or issue. It pulls away from parked position without issue. Appears to accelerate just fine. In stop-and-go traffic or directly onto the highway it seems to run smoothly without problem. After a period of time (I don't believe it to be consistent), it will start to misfire and the C.E.L. will be set. If it is still misfiring, the light will flash.
Here's the weird part...when stopping at a traffic light or just continuing to drive on the highway, the misfire will resolve and the car will run smoothly again. The C.E.L., trailing the condition by a bit, will go to solid from flashing and will remain that way until a little farther down the road. The misfire never seems to be more than one cylinder and the trouble code seems to bear that out. Just idling, the car will return to smooth operation and it seems to have smooth acceleration. In other words, the misfire seems to go away under acceleration.
What I've done: I've replaced plugs and wires. No change. Replaced Coil pack. No change.
Next steps: Next steps seem to be looking to fuel or air. My concern with that approach is the occasional nature of the problem. Compression problems would be consistent across the board, right? That cylinder would always be a problem. Same thing for fuel (fuel pump and/or filter). All cylinders would have the problem and it would have issues starting. OK, next thing--injector. Would an injector have spotty performance like this? Also, could it be related to the EGR ports on the intake on this vintage Windstar? (Once again, is an intermittent problem consistent?) Finally, since the primary circuit for spark is controlled by a PCM pin setting a ground for each cylinder, could the PCM, or wiring, be the culprit?
Camry :: 2 Ignition Coil Failure - Engine Code P0302
Just a few weeks ago I replaced a bad ignition coil because I got the engine code P0302. I replaced the spark plugs with NGK Laser Iridium and the second Ignition coil. Now a few weeks later the Ignition coil 1 has died on me.
View 1 RepliesPassat (B5) :: Misfire Detected - Error Code P0322 And P0302
I bought my first VW about 3 months ago (so excited!) It's a 2003 Passat, 5 spd, 1.8t. I've had one thing happen so far (until yesterday). On 4 separate occasions when I'd go to start it, it would crank for a few seconds before it would start. Then once it was running the EPC light would turn on. It seemed to be running normally but I turned it off and restarted it and it started normally and the light extinguished (the first three times). The last time (about a week and a half ago) it kept doing it each time I started it, and upon starting probably the 4th time in a row the MIL came on. I drove it about a mile, turned it off for a few minutes, then turned it back on and it started normally with no malfunction lights on. It's been normal since then. Until yesterday...
Yesterday as I'm accelerating from a stop light (I think I was in 3rd) all of the sudden the engine started running really rough and the MIL came on. I turned around and drove about 2 miles back to where I started at about 20mph. The MIL would be steady while coasting and flash while pressing the accelerator. I got a hold of a diagnostic computer and it came up with 3 codes...
1) P0322 Ignition/Dist Engine Speed Input Circuit No Signal
2) P0302 Cylinder 2 Misfire Detected
3) P0302 Cylinder 2 Misfire Detected PENDING
Subaru - Forester :: 2002 - P0302 Code With A Miss Only When Idle
I have a 2002 Subaru Forester L with 178,000 miles on it. I just had the valves adjusted. I have replaced the coil pack, #2 injector, plugs, wires, and throttle position sensor. I have also cleaned the idle air controller. The car only shows sign of a miss when it idles. It gets great gas mileage otherwise. I am at a loss on what to do next as the car doesn't have a MAF sensor, I can't do anything with it.
View 19 RepliesAccent MC (2006-11) :: 2010 GL - Misfire On Cylinder 2 / Code P0302
I have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.
