New To Spi Engines. Help


Best Answer FlyingScot , 07 February 2016 - 08:59 AM

UPDATE. I found a small split in the pipe which connects inlet manifold to fuel trap. Replaced that and it's running perfectly. I will give it a good long run now and warm everything up and see how we go.
I have also replaced my alloys with the orignal steel wheels and wheel trims that where found on the 1995 sidewalk. It's now as oringal as it left the factory.
Thanks everyone. I will get pictures up soon


The 3rd answer to your original question....

lots of pipes to the air filter check them all for splts
 
there is also a Little black box to the left of the spi unit on the bulkhead if i remember correctly with 2 pipes to it check them for splits

Did you get your coolant temperature sensor from mini spares?

New stepper motor fitted, but I'm still getting the same problems. As son as you slow down and dip the clutch the engine will stall, i have read I think so,we here about RESETING the stepper motor, can someone point me in the right direction......
I have tired to adjust the throttle link which I found at the back of the carb (little 7mm nut on a small screw that turns and pushes against the pin for the stepper motor.

Do not adjust the stepper motor stop (idle screw) without diagnostic gear. Resetting the stepper motor can be done by testbook or Crypton ACT.
It cannot be done by pressing the throttle 10 times unless you have an early SPi system with the throttle switch.

What have you checked so far? Vacuum pipes and fuel trap? replaced them ?
You have to work logically through the information on the pinned threads. Diving into "I've had a smiliar problem and it was.." wont help.
The system tries at all cost to keep the car running despite sensor failures misadjustments etc but relies on the fact that your then local Rover dealer would plug it into Testbook at service time or when you found an issue and determine what was amiss.
If you don't have diagnostic gear and can't buy or borrow some you need to go through each step carefully.
Most problems on SPi cars are due to lack of maintenance (vacuum pipes, sensors etc) and deterioration (wiring, lambda, stepper motor coils relay packs etc).
Have a look through the the pinned threads and also the one on having a code reader and look to see if there is someone local to you who could help.

Thankyou flyingscot, the reason I asked a technical question on this thread was because some one who gave me advice said "if you get stuck ask again" it was related to the topic, I apologise it wasn't in the thread wasn't in the right section....I have been working my way through the pinned threads and checking things logically. I just wondered if there was something I had else or if some,one did something different to me.

I appreciate all the advice, still learning my way round the spi and apologise if I've repeated questions or annoyed people by using the wrong sections

Definitely not just you or you...

I am just trying to learn and contribute as best I can...

I don't have a lot of direct experience with SPi, though I have helped sort a few.

UPDATE. I found a small split in the pipe which connects inlet manifold to fuel trap. Replaced that and it's running perfectly. I will give it a good long run now and warm everything up and see how we go.
I have also replaced my alloys with the orignal steel wheels and wheel trims that where found on the 1995 sidewalk. It's now as oringal as it left the factory.

Thanks everyone. I will get pictures up soon
