Just finished valve seals

[colinmartin]

Had a problem with the valve seals,which have been replaced but the engine was taken out, whilst it was out replace front and rear crank seals and cleaned the injectors ,put engine back in coded the injectors through rheingold , everything seamed ok , but now it keeps throwing errors , the engine was washed before it was put back so some of the electrics might have got wet

Any ideas where i should be looking, it would have been nice to actually have the car fixed for once , rather than always needing something ,

Just sell it. Why keep wasting money ?

X5m running like crap ,practically worthless

I don't know what balanced throttle factor means but might be worth checking to make sure you don't have a vacuum leak somewhere. I realize that's a tall task buts it's got to be something simple like that?

[colinmartin]

thanks I have been looking all day now the exhaust doesn't open when you hit the m button and for some reason the max a/c doesn't work f*&king car

[philly42]

I would start by replacing the upstream o2 sensors. If you have rheingold it'll narrow down the problem by telling you which code is really causing the problem. Then you can run tests within the system to confirm. At the end it'll spit out what parts needs to be replaced.

[philly42]

FYI, If the throttle body angle from one bank deviates greatly compared to another bank it'll trigger a code. There's many possible causes for this. If you get the code at idle, it could be related to the ccv system, huge vacuum leak, or o2 sensors. Under load it could be related to a vacuum leak or o2 sensor.

o2 sensors are really sensitive and can damaged easily. The good thing is they're easy to replace. Just make sure you wire them up correctly to the right bank or else you'll get a shit load of codes. It was easy to spot the issue in rheingold as there's a code related to the wiring of the o2 sensors.

Why would you code the same injectors? Also, pulling the motor , R&R injectors, and swapping out the valve stem seals is a large undertaking. Any number of things could have occurred such as crimped wiring, plug not fully inserted, timing, damaged injector, etc... Me, I would grab a good light and inspect every wire incl ground, plug, and hose. It does not take much t get where you are at. Hopefully you disconnected the negative battery terminal first.. GL.

the reason for the recode of injectors is that the Rheingold had a different set of numbers stored not relating to any of them ,I chose to have the injectors cleaned while the engine was out ,I am going to get my light out today and do exactly that, and yes the battery was disconnected. I must say that the mechanic that worked on my car is a family member and has done numerous things before he is very methodical

the o2 sensors are almost new as I had just changed them when I installed ar sports cats about 3 months ago,i also change every vacuum pipe on the motor I did notice that the pipe going into the crankcase number 1 in pic had a bad o ring so I changed that yesterday

I have notice now it backfires when decelerating and it is idling just below 500rpm

Codes still the same? Have you reset adaptations?

yes I have reset adaptions

[Sophisticated Redneck]

Most likely your Injectors if you are 100% sure your 02 sensors are solid and no vacuum leaks. Either they were damaged when cleaned or something is up with your coding. I would double and triple check you coding of them. If you have the $$$ Then I would say just install a new set and be done with it.

just checked the injectors they are runnning perfect ,rechecking throttle bodies now incase of leaks .

[philly42]

swap out those o2 sensors then reset adaptation. It's one of the cheaper items to replace in fixing this issue. start there and work your way up to the costly injectors.

Make sure that the vacuum lines running along the top of the motor are plugged into the black vacuum canisters on both sides of the engine. Make sure they are on tightly. I had a scenario with similar issues where I tightened the vacuum canister downs and one of the lines pulled off on the back and I didn't see it. Not sure why these don't have hose clamps on them.

What are you using to scan your car and does it have datalog or have a live view? If I were in your shoes I would be logging the air/fuel, vacuum, fuel pressure, throttle plate angle, etc of each engine bank and comparing the two for variances. A quick a dirty one that is easy to hook and does data logging and live views is this: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1. This is how I caught my bank to bank boost variance and also intercooler temp variance. Easier then a laptop =)

I have been using my Carly, but the mechanics are using Rheingold ,funny thing happened last night my carly couldn't get comms from the engine ,I must have tried at least 20 times I'm thinking when they put the motor back one of the connections is either weak or not connected. Its going back in today to see the electrician to see if he can find anything. I have an appointment with the tuner tomorrow to update my tune and put it back on the dyno

[colinmartin]

Took the car to the tuners today . They took it back to stock and its still popping and backfiring on deceleration , they reckon its the injectors . I cant believe taking the decision to clean them prior to putting the motor back in has somehow screwed them up, anyway i have bit the bullet and ordered 8 as they don’t carry them in stock here and I don’t want to wait ages for them to turn up 1 by 1 , hopefully after this i might have an improved car , to be honest that would be the best christmas present ever

[9vapors]

You could just test them in ista instead of buying all 8, but replacing them can't hurt either

[colinmartin]

for some reason the guy that has the Rheingold and ista has light version of the software ,because mine is an early 2009 it doesn't have all the functions
