Hi guy's i have this strange holding back issue thats been bugging me for a couple of week's now. I really need to sort this problem as i am planning on turning up the boost but don't want anymore damage to happen just rebuilt the bloody thing :lol:
Sometime's when you hit full throttle there is a surge of powerloss which comes and goes it sort of feels like heatsoak like when i had the tmic. Also the exhurst note deepens slighlty. Hope this makes sense as it's a bit difficult to explain. :doh:
I have rebuilt the engine replaced dizzycap and rota arm plug's 1 grade colder and plug leads set the timing. plug's and leads made it better but i still feel it's not right. Boost is ok every time your at full throttle the boost gauge is just about touching 7.
Whilst i was out last night this problem accured again and when this is happening i tend to lay off the gas incase off it will cause damage to the engine. noticed my fuel was getting low well it was getting close to a quarter and was a few miles out of town.
About ten miles down the road pop's a shell garage so i swing in there and stick £20 in. Pulled out the petrol station and the problem has gone pulling nicely all the way up the rev range. And for the rest of the journey. Got back in the car today to go do some work on my mates car and it's back still plenty of fuel in around half a tank.
So i was thinking about it some more today no fault's in the ecu memory btw we can see this fault is either ignition of fuel related. Had a few item's changed on the ignition side now i'm looking at the fuel side a bit.
I have a walbro pump thats done about 2-3k in the car. But because the fault went after i had put more fuel in maybe the fuel pump filter has come off and is restricting the fuel pump from doing it's job as more fuel the pump filter will float higher away from the pump and not be able to get sucked up by the pump.
Or i could be taking shit and it could be some thing to do with the ignition side.
Any help would be great guy's starting to do my sweed in a bit now want to get the thing quicker.;-)
