SOURCE: is there any bad effects of blanking off the egr

Hi,
yes, there will be a bad effect if you do that. The ECU will not be able to exercise it's engine management role correctly, and the performance of the car will be affected.

Good luck.

98 buick regal tries to crank but floods the plugs what is the problem


Yup. Fuel supply problem. Could be a number of things. Check if the injectors are clicking when you crank. no click, no power to the injectors, problem with sensors data to the Ecu. If click, that part is not the problem. More likely Fuel pressure regulator is bad, not enough pressure, or fuel pump relay which controls the fuel pump. So either may be bad or connections are bad or wires cut. Fuel filter may be clogged. To test th fuel pump, you can jump from the battery positive to pump terminal for a short time to verify the pump is good. so then connections at pump, or from the fuel pump relay or it's connections to the ECU. Most disastrous may be the Ecu itself. Other sensors to the Ecu could contribute, but usually with code problems including sensors it goes into a "limp home" mode. overriding bad sensor inputs. If somehow you can get the error codes read at auto parts store, that may give you more clues than I can guess at. Good luck, hope this helps you out. I gave this answer to another query, but most of it applies in the opposite way, you are getting too much fuel (we used to call it flooding)

How do i fix ecu on a volvo v70 2.4 petrol non turbo giving a misfire on No 1 & 2 injector current


Google ecu repair for your vehicle. Most likely dealer, and not cheap! Sorry.

"I have a 2006 Nissan Pathfinder 4.0 V6... Had ECU replaced . Now is throwing a random misfire code P300... what are these code and can one cause the other? Help!"


code p300 refers to random/multiple misfires--misfire detected==causes--spark plugs--HT leads --injectors--ignition coils--low compression--wiring
If you are only now experiencing the problem after changing the ECU, I would suspect that wiring and connections to the new ECU may not have been fitted properly. There may be problems in the ECU CPU (chip) and it may be necessary to use a scanner to reset the CPU program to recognize the sensors of the vehicle correctly

Is there any bad effects of blanking off the egr on my sangyong rexton 2.7 i have heard that the ecu recognices it as a fault

97subaru impreza outback sport wagon 2.2 1234 misfire replaced plugs ,wires, coil pack, fuel filter added injector cleaner check engine light blinking with no code.what do you think i should do next?


check you ecu. same problem happen to me in an izuzu rodeo. I let my fuel get to low and it sucked dirt into the filter and messed with that and it set off a code for the ecu and messed it up but if i had just replaced the ecu first i wouldnt have had to change the injectors or anything.

What is involved in a tune up


if petrol - spark plugs, air filter, fuel filter, throttle body clean, ignition timing check and adjustment, exhaust gas check, carburettor adjustment, valve tappet adjustment, ECU code check/scan. fuel injector clean.

if diesel- air & fuel filter, tappet adjustment, check glow plugs, scan ECU, drain sedimenter, may require injector clean and/or fuel timing adjustment.

if your car has a running problem get it diagnosed first.

I have a 99 Ford Taurus that keeps showing a code PO301 #1 cylinder misfire. I have changed spark plus first, and it came back on. I next changed the wires and it came back on. I took the coil to Autozone,...


If the plugs, wires, and coil are all good then it can be a partially clogged injector, or low compression on that cylinder. It can also be a bad ECU. My cousin had a 99 Taurus with the exact same problem and it turned out to be the ECU which he had to replace. The ECU is very expensive so make darn sure everything else is good before you replace the ECU. It could be the coil has an intermittent problem and may show good especially when cool. You might try putting that coil on a different plug position, resetting the ECU, and see if you get the same code PO301. Run a compression test on all cylinders to see if you have good compression. Add a can of Seafoam Fuel Treatment to a full tank of fuel to make sure the injectors are clean. Check all wiring closely for frayed wires or loose connections. Eliminate all other possibilities before looking at the ECU itself.

1991 acura integra power loss, won't rev over 3000rpm code 16 fuel injectors. changed injectors and fuel filter. air/fuel meter not reading.


check the o2 sensor if thats not it something maybe blocking your intake and if thats not it then it could have something to do with the computer (ecu) check the cables that connect to the ecu cause my moms cadillac had the same problem so just disconnect the ecu plug it back up
