2006 128k on the clock. Decided to do an injector cleaning last weekend. OTC canister, BG cleaning solution. Ran the canister dry and let the Rover stall. Pressure was 58, 60 psi. Flooded the engine so bad that it took no less than 6 WOT (pedal to the floor) cycles to get her cranking back up. Question. Is it normal for it to flood so bad? My understanding is the pressure on the injectors is 65 psi, so if anything I was giving it less than what it normally runs at.

 

I guess I'll ask it this way. When some of you guys performed this type of cleaning, did you experience what I did? I read some of the threads and all of them mention some degree of flooding. I just never thought it would be so pronounced. I remember doing this on my old Ford back a few years ago and it had fired right up.... I know, 5.0 Windsor isn't the 4.4 Jaguar...

 

I've had luck with simply pouring BG44K into a half tank of fuel every other month instead of running it through the intake/vacuum system.

My MINI cooper however being direct injected I ran through the intake, and I had to keep the RPMs at 2500 and spray in short bursts so it wouldn't stall.

 

Never had one flood. I put the Fuel Pump relay back in, cycle the ignition to Pos 2 twice and fire right up.

 

Interesting. What Rover magic happens when you cycle the key to position II twice?

 

Cycles the fuel pump twice would be my guess

 

Ah, of course... Fills the empty fuel line, delivers the gasoline to the rails.

Another observation. There is a video on YouTube of Storey Wilson (of the RSW Solutions fame) performing the cleaning and he mentions that he gave it 35, 40 psi. Basically half of the pressure the rails normally see. As far as I can tell he had no problem afterwards... Anyway, it is academic at this point. Just curious and thought someone might use this info in their case.

Thank you guys. Glad we have this forum to share ideas and insights.

 

Good guess.
