My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

This may be an issue with a lack of fuel to the engine.When the wheels are on the ground and accelerating the engine is under load and if there is a lack of fuel this can cause this fault here.I would check to see if the fuel filter needs replaced.If this is o.k. I would have the fuel system tested for any issues.If all of this is o.k. then I would have the exhaust tested for excessive back pressure due to a restricted exhaust component needing replaced.If these were all already checked let me know.

Hi thanks for your reply. Sorry the fuel filter was changed and was and fuel system is fine.
Just a thought it's started to kick out black smoke an sometimes blue when revving engine. Would this be maybe part of excessive back pressure? What's the causes of that a blockage somewhere? But if there was a blockage would it work while off the ground. I also forgot to say the van doesn't really stall when going in reverse

Were the fuel injectors replaced at all or tested?

Customer: replied 4 months ago.
No they wasn't. But mechanic that came out said they were ok as the van would sit idleing for a long period and also van will drive in reverse without a problem

Does it smoke at all when drove in reverse?

Customer: replied 4 months ago.
a little but not as bad as when sat idoling or trying to drive off forward
Expert:  Peter Zavarelli replied 4 months ago.

This can still be a fault with fuel injectors.I have seen these act up under load more then when at idle or moving slow in reverse.

If you can I would have the injectors tested to see if one or more are faulty needing replaced.If one or more are faulty this can lead to excess fuel in the exhaust which can lead to a plugged exhaust component as well.It is a good idea to have the exhaust tested as well as the injectors.

Let me know if you need anything else and feel free to rate my help here or above ( should be a link to click on ) as this is how I receive credit for my time,this can be done at any time and you can still come back here and reply if needed.Your 5 star rating is appreciated
