MAF..no Lambda..no What is going on? Please Help.
So I was driving home from work yesterday and all of a sudden I push the accelorator and the car loses power almost to 0 then randomly goes again then almost stopes 10m down the road then started going normal again....
Then I pulled into my driveway, So I was reading online, could be the MAF or the Lambda....so i disconected all of them seperatly.....MAF made no difference, and if I am correct there are 2 Lambda sensors? I disconected them, that just made black smoke come out the back.
When I try to start the car it starts and it goes to about 3000rpm and then as noral it drops and instead of stopping at like 700 it just coughs and turns off.
There is no power or something......the Injector light abouve the code key came on yesterday morning....and is still on, even after i disconected everything.
So I hooked up my laptop to car via alfadiag and it's reading the code as P1688 (there are so many definitions of what this is .....it's is aparently either one of these.
- throttle valve
- Metering Oil Pump Stepping Motor Circuit Malfunction
- Internal Fuel Injection Pump Controller Failure
Any help would be so appreciated, I checked all wireing it all looks good to me.....
Just got the car back 2 weeks ago after full replacement of gearbox and now this......I dunno how much more I can take, hope this is a quick fix as I was going to change cambelt this friday in Gosford....but dosn't look like I can get there...
