Passat (B5) :: Code 1136 / Backfire And Immediately Stall If Rev Engine To 3000 - 3500 RPM
Nov 22, 2006
Looking for a good diagram of the complete vacuum system on the AEB 1.8t 99 passat. I am throwing a 1136 code which is indicated as a "Manufacturer controlled fuel and air metering". I recently finished a complete rebuild and engine is finally back in but running in limp mode. During the rebuild, I used mobil 1 synthetic as an assembly lube for all internal components including valve train.
I immediately wet fouled O2 sensors and spark plugs. After repeated removal and cleaning for plugs and O2 sensors i have progressed beyond seeing the "wet" fouling but plugs are still very rich, black in color but dry. Engine starts and runs at idle(lumpy) consistently and will run for as much as 5 minutes but very rich. If i rev engine to 3000-3500 rpm it will "POP" or backfire and immediately stall.

Symptoms- won't rev over 3000-3500 rpm's, upon acceleration (especially uphill) seems to struggle and won't accelerate much at all, seems as if trans changes fine. BTW, throwing no codes at present.
What I have already tried...new air filter, new fuel filter, had cat. check (was told stopped up but when removed found it was not and truck did the same even with cat. off), o2 sensor (upstream) replaced, battery disconnected to reset computer.
After reset of computer, runs a little better but still not good. Seems to start if you accelerate to quickly or when truck reaches around 40-45 mph.

5 miles to the airport last night, cruising on the freeway, my transmission suddenly accelerates from the steady 3000 rpm to 3500 rpm. When I press on the accelerator, the engine speed and my actual speed are no longer in sync. It feels like the transmission is no longer shifting. The radio cuts out and all the lights dim. My airbag warning light flashes intermittently at me. I make it to the airport, afraid to turn the key off; but I must. I attempt a restart - nothing. All red lights but no engine cranking. What gives? A fuse, the alternator? The car - 2003 mazda protege. The driver - stranded when I return home.

I've got a couple of issues with a 2002, 2.7ltr v6 santa fe first off when taking off steady the car runs fine but taking off quickly it seems to lack power until it hits around 3000-3500rpm est then it takes off fine and all threw the upper rev range the auto seams sluggish but I'm not shore as I haven't driven another 2.7ltr as a benchmark. No error codes are present.
The second issue I brought a new keyless remote for the car and looked up a thread on how to program this they had reference to a set switch behind the fuse box behind the lower dash panel I went looking and found what I think is the remote receiver it has what is like a antenna cable plugged into it but no set-off switch at all is there any way to get this new remote programed or will it have to be done threw dealer or is there something I would be missing?

Car: 1995 Corolla 1.8L automatic
Symptom: misfires around 3000-3500 RPM only when warm.
I have replaced the following:
-Spark plugs, wires, cap, and rotor
-Ignition coil
-Fuel filter
-Poured some quality fuel system cleaner into the gas tank
The car stutters when accelerating in any gear hard enough to reach the engine speed that the misfire occurs at. It doesn't backfire, it just misses... I am confused since so many of the misfire issues I know about that are RPM specific are spark-related.
I have considered cleaning the injectors, but don't want to go through the hassle to remove and have them cleaned unless I really have to. Checking if hunch on the injectors is correct? Something else?

My 1994 Acura Integra makes a buzzing noise exactly between 3000 and 3500 RPMS. It sounds kind of like the sound a circular saw would make cutting wood. It only happens when I am accelerating through that range. Also, sometimes after driving for a while, it doesn't last as long and the noise stops around 3300 RPMS. I've checked the heat shield and it seems to be fine so I don't think its that. What this could be caused by?

My 302, only mod is a 4160 600cfm and i love it. But when I kinda baby the throttle and the secondaries flop down to let fuel it... There is a massive lag time. Sometime it will even backfire! fronts have 59's (could be slightly richer) and the back has a 134-39 metering plate and a black spring. it seems that it needs another shot from an accelerator pump to keep going. I raised the float with the same result, how to cure that lag time without mashing the throttle.

I recently bought a 2004 V10 TDI. When it is quite cold outside, below -15C my Treg will not start, it starts sometimes but will stall immediately. I cannot get it started unless I wait a few days until it is warmer out. When I start it, I wait for the glow plug light to go out but it only takes less than a second, is that normal? I am thinking its the diesel gelling and I need to add an additive to it possibly, or do I need to replace my glow plugs. If I am persistent, I can sometimes get it going after 10 or 12 attempts but I feel I am going to overheat the starter so I am scared to do that often, once started, it runs fine but has tons of CEL codes which are all glow plug errors, I will clear them off, and they will not return.

I have an 2002 Dodge Grand Caravan that cut off shortly after starting the other night. Every time I try to start it, it will crank and then stall almost immediately. I tested the fuel pressure and it was strong so I hooked up a pocketscan and my van starts and runs normally while the pocketscan is hooked up. I even took it for a drive around the neighborhood. As soon as I unplug the pocketscan my engine shuts off. The only code on the scanner was for the O2 sensor(not something that would shut my engine off.)

I have a 2001 santafe with a 4 cyl The code 102 was up so I replaced the mass air flow censer . I go on a test drive and the light stays off , but when I go to re start it again the light come on and stays on, with the same code. The only strange thing is the idle will raise for a min then drop down to almost a stall.

Long time Ex owner. This is my second 2000, 4wd, Limited, 6.8 V-10. Just bought this one last month and after two weeks of local driving the following problem showed up:
1. Week of July 5 through 11: With vehicle cold (65*) started and placed in reverse to back out of garage. After slight movement engine stalled like a locked up torque converter or turning ignition off. CEL illuminated. Turned off ignition and restarted. Again in reverse had same stall. Third time no problem but CEL still on. Code is P0720 using "Actron Auto Scanner."
2. Erased Code P0720 (OSS circuit malfunction) and P0307 (Cyinder 7 Misfire Detected). Drove car approx 20 miles without incident. No stumbling, no vibration, no detectable misfire, shifts okay, speedometer okay.
3. Next day with vehicle cold, started to back out of garage and stalled with CEL illuminated and O/D light in shifter blinking. Recycled ignition, started and no O/D light but CEL still illuminated. Vehicle did not stall. Checked code and P0720 set.
4. Replaced OSS on tail shaft of transmission. Same stalling problem with P0720 set.
5. Replaced #7 COP w/aftermarket type to test possibility of bad COP because of earlier P0307 DTC. Same problem exists, first start of the day the vehicle will stall as soon as it starts to move in reverse.
6. Replaced rear ABS sensor. While doing so noticed the ABS sensor wire harness was rubbing the tailpipe and the split, wire conduit was partially melted. Inspected wires (2) within and both appeared okay. Safety wired the harness away from the tailpipe.
7. Let the vehicle sit awhile. Outside Air Temp 84*. Started, placed in reverse, moved a couple of feet and engine stalled and O/D light on steady. Recycled ignition and started again, backed out with no stall or warning lights. No CEL on. Drove 10 miles without incident.
8. Allowed vehicle to cool, started and attempted to back out of garage. Engine stalled, CEL illuminated and O/D light flashing, code P0720.
9. Sunday morning 12 July: 71*, Allowed vehicle to idle in P in garage for 10 minutes before trying to back out. Vehicle did not stall. CEL still on from previous day, no O/D light. Erased P0720 code. Vehicle operating normally.
10. Sunday Noon 12 July: 85*, Started, placed in reverse, backed out and no stall or CEL or O/D light.
After considerable research online at ford-trucks.com found P0720 is a common problem but not easily diagnosed. In most cases the gremlin is COPs and or deteriorated plug boots but in this situation the engine appears to run smoothly and the failure/errors only show up when the vehicle is moved in reverse gear after a cold startup. Once it stalls then restarted it runs fine.
Made a quick check of alternator for failed diode using DVM since I don't have a scanner. Checked okay for voltage and AC ripple. I do have an appointment on Wednesday with my local auto repair shop for troubleshooting. Will have them do continuity check between OSS and PCM and an AC ripple test. Does this sound like an electrical circuit problem or internal transmission problem? Want to make myself as smart as possible when I talk with the techs.

My 04 F150 has started having a rough idle. While in park the engine will stall out with the A/C off. Also when in drive the truck will idle close to 1000rpm's. I had to the fuel filter cleaned and also the MAF sensor cleaned. Also did a vacuum check on it. Pulled the code and it's throwing a Lean Code. What else should I be looking for?

Having problems with start up? It feels like the engine wants to stall when I start it and as if the flywheel is so heavy. It also like jerks the car. You can clearly tell it isn't a smooth start up. Maybe the starter?

I just had my 25k service a month ago. Left car in MSP airport lot for a week and when we were driving home to Duluth last night, the check engine light came on and started flashing and the engine started to stall and run very rough.
Drove slowly to get home, noticed HUGE burning smell under hood, opened it and this part under engine on left side was a glowing fireball red cylinder. 1.8t, have all my maintenance done at dealership. Car ran fine for 126 miles on the way home and it just came on and started flashing

I have a 06 Passat with a V6 with 80K on it. Recently I have been getting intermittent stalling at start up, only when the engine is warm(but once on a really hot day). The car will rev slightly and stall. After several attempts, it will start, and then it runs fine. VW service said no error codes and didn't offer much more.

Wanted to ask B6 owners first, from time to time I hear what I think is a backfire after doing a hard pull in 3rd but never in 2nd. Now I'm not sure its a backfire but after I shift to 4th I hear a small pop from the back of the wagon. Don't know if this will happen in 4th after a pull, have not had enough road or balls to do this. ( In Oregon you get a huge ticket and license pulled for 30 days for anything over 100.) Everything runs fine, I only have the Neuspeed intake for the autos and thats it. Any thoughts you B6 owners have B4 I go to the 2.0 fsi page would be great. Here are some pics from the big snow storm we had here in Portland back during xmas. The Thule chains worked great when I was not high centered.

OK about 3 months ago I bought my first vw, a 99 Passat 1.8t. Car was great. Only problem at the time was a loud backfire while down shifting no clue on y either. Let me say this is my first turboed car too. Anyway after about 2-3 days my cel came on. I threw my scanner on it and got evap leak. I filled her up right after that and smelled real bad gas. Found a screw hole in the trunk patched it cleared the code an she ran great again. Well for a few days now after every fill up I have to keep my foot on the throttle or it stalls out. Keep getting same code. Also when I go to jump on it it'll like studdar an hesitate before going. No more gas smell either. The kid I bought her from did some work an I'm getting 15lbs of boost but at times will jump to 17-18 lbs. I have no problem doing the work to get just need some guidance on what to do. I've been told change charcoal canister, fuel filter charcoal canister purge valve, I guess there's 2 cause I was told to change both. I love this car, this is the best and my favorite car I've ever had. J wanna get her all nice and healthy.

I have a 1 ton 2000 GMC sierra (old body style 99') 7.4 liter V-8 Gasser with the Allison 1000 tranny, 4x4. the engine will not crank over..
Battery was dead so I charged it, battery was holding 9v, so i hooked up jumper cables to my new car, gauge showed 12v, so I tried to start the truck.. the fuel pump, antilock brake system, and gauges came on.. as well as the "check engine light", "service engine soon", and battery light... I ensured the trans was in park, even tried neutral.. no crank.
I hooked up the mini scanner tool I have, and got no codes.. cleared the ECU/ECM anyways.. no crank.
I also tried swapping out my starter relay with the A/C relay, and pulling fuses to the ECU/ECM for 20 seconds to clear any issues/codes.. no crank
My next option is to clean the battery cables & terminals (or replace the cables), and replace the battery... the battery is only 2 years old.. due for replacement, but I'm kinda broke right now. The battery is one of those stupid side terminal ones with poor connections to begin with.. is there a top post terminal battery I can get to replace this POC? or will the posts hit the hood?
This is a plow truck, single battery setup (at the moment).. and the fisher 8' plow when running the hydraulic pump severly drains the battery.. lights dim severely, been wondering about a higher rated alternator (factory is rated at 120-140amps), larger power cables... etc.. dual battery system...

I lamented in the past a lot of vibrations when the engine was at 3500RPM (in any gear). I read on the forums and many people blamed the aftermarket "EMPI" axles that I mounted too. In fact, my OEM outer CV joints where seized inside the hub/spindle and one of the inner CV joints was clicking; the boots were all worn. This was the reason I went with aftermarket axles. Anyway, I rebuilt the OEM axles by keeping the shaft only, and getting good quality inner and outer CV joints. I finished today to swap back the OEM axles and, finally, no more vibrations!

Yesterday I punched it and seemed the truck was a bit doggy at higher rpm, the cel blinked but no codes, drove it all day today and it still seemed "not normal" I punched it and it wouldn't go past 3000 rpm and its so doggy it barely moves got a code po141 engine seems like its super lean? This happened on my way home luckily about a mile from my home.
