This is a picture of the speedo drive I need (cut and pasted from Pollymobile bloghttp://www.micra.org.uk/threads/pollymobiles-rebuild.35251/page-22 ) Paul has measured the speedo drives the gearbox hole & electronic speedo was 36.75mm dia while the mechanical speedo was 37mm. This is the one I need
Car is back on road. Only problem now is I have acceleration issues it hesitates quite aggressive on fast acceleration. Sometimes it doesn't let me rev past 3000 rev when it gets warmed up. I am going to change throttle body one more time, I may have got another bad one, as it was re-sealed suggesting someone may have repaired it previous.
I have a few issues at the moment in the lower revs I have the following two issues:-
1. At standstill when I press the accelerator the revs drop a touch then pick up
2. While driving at the lower revs the car seems to hesitate so I get a bouncing motion as I drive. When I drive in the higher revs the boost kicks in and I can't feel it, But I feel something is still there holding the car back.
I have disconnected the AEM Fic with similar issues.
I checked vacuum lines and plugs. They seem ok.
Strange problem, it seems to happen when the car is warm and When driving in low revs it is bouncing forwards instead of driving forwards smoothly. When I floor it it goes away and it seems to be holding back.
Any ideas ?
+1 ^ the ecu uses the feedback from the lambda in order to run closed loop, but there is a limit to how much the short and long term fuel trims can cope with.
that 300hp fuelpump is probably overpowering the system ?
I opened up the dizzy today completely different to the one I took off a Micra. Anyway I put some insualation tape on some of the plastic casing over the wiring connections as they were cracked(they are not rubber cased like the micra dizzy).
I put the old one back in the car. It ran for a while even drove a few blocks. Restarted all ran ok. It seems like a dizzy problem to me, getting the same one for my car is not easy (it is a 7 wire connector). I have decided to put a micra one on and put the extra connectors onto my loom.
I hope it will work what do you think Frank, Enuo, Paul etc..
Does anybody have the two connectors that connect to the dizzy?. I want to connect them to existing loom so I can plug in Two connector Dizzy
