Cleaned aac valve out and all pipes around it, then went in to throttle bods and toothbrushed everywhere and squirted carb cleaner all over the place till u could eat your dinner out of them but she still hesitates almost cuts out if the revs are low to start off with??? wonder what else it could be, been on nissans diagnostic machine but shows up no faults any one else had this prob??

Not a clue,but sounds like fuel pressure at tickover not stable!just a guess:confused:

Crap fuel,coils/plugs,AFM,:confused:

The aac value should be cleaned after the TB's as you probably have this full up with debris from the TB's now.

 

Although I don't think this is your problem.

The next thing to try would be clean each of the connectors. Start with the injector connectors. These are very fragile so be careful. Some of the contacts may be corroded which may be causing the problem.

I was suffering bad starting problems and hesitation when cold a little while back. This turned dampener. Only guessing but it was like a whole bank of cylinders was being starved of fuel. It's difficult to describe how to diagnose, not being an expert, but Jeff showedhe serviced it first that the small pipe furthest to the left on it pulled off easily and his term "was a bit damp". You might want to give him a call at Zedworld to ask about this.

I have this hesitation problem. If I was at traffic lights and tried to move away the revs would almost cut out and then the car would start moving.

 

In the end the car completely stopped working.

 

Found out it was 2 temperature sensors......, £20 each. Works fine now.

 

Could be this....

sounds like it could be a temp sensor....or have you checked you TPS....is it giving correct voltage,i think it is 0.4v...but i am not sure...this was the problem on mine anyway,since lack300 set mine up it has purred..........

have you checked your TPS sensor...this is set at 0.4volts..i think...this could be your problem,it was on mine anyway.....

thanks guys i will try to get a sparky to look at tps as i think its this too, i havent a clue how to measure .4 volts im brill mechanicaly but inexperienced with electronics:eek: :eek: :eek:

its very simple you just measure the voltage accross two wires going in to the sensor?which two i cannot remember.sorry.if you email lack300 he will tell you...he did mine..this stopped the hessitation straight away....:D
