12 & 52.

It's running like a dream.

Fires up and revs freely.

Not given it any stick as it's running in.

Why say that then, doesnt need to run in.

I've changed the big end shells

 

[weakboy2]

inlet side of the block???? or are you talking about the head?

doesnt matter what side, it would have had a cooling system issue and overheated, hence why the original gasket failed i would imagine, or a result of.

Big end shells dont need to be run in. just change the oil after 50-100 miles to get rid of the small amount of swarf.

 

[Sigma]

Yeah, the inlet side of the block had one or two highspots around the studs.

 

[weakboy2]

oh well should be all good now matey. still selling it?

 

[Sigma]

If somebody's prepared to come up with £4k, I'll let it go

If they don't, it'll be a garage queen for another year

 

[ragz]

can a knock sensor go faulty over time my mates ep keeps coming up wiv fault code 52

never come accross one on this forum

 

[Sigma]

Just like everything else, I'd imagine, Ragz.

I've got a spare to try, but I think it's the plug tbh.

Will report!

 

[ragz]

had a look at it today it seems his knock sensor wire had split before and was soldered back together

took it all off n soldered another one to it as the previous one had a messed up clip, but still no joy

also i know its off topic but what would cause a car to switch off when stationary, drive perfect but come to some traffic lights and its cut out

tried idle control valve and map sensor

thanx in advance n sorry to invade your thread

 

[Sigma]

TPS settings, had this exact issue with a Pontiac Trans-Am V8, the voltage was out and stalled it at the lights.

 

[ragz]

cheers for that sigma will have a look tomorrow

 

[Sigma]

There's a tutorial somewhere regarding it, explaining exactly how to get it spot on

 

[ragz]

will look for it now

nice one dude repd

 

[Sigma]

Got 12 & 52 fault codes, both relating to engine rpm signals.

52 is the knock sensor.
12 is the ECU not receiving an RPM signal.

Just me that thinks that this will be the same fault?

If so, any hints?

Have you reset the ECU and checked if the codes have reappeared?

If code 12 was an active fault then it's likely the engine wouldn't run or just start up and then cut out. The ECU should cut the ground to the fuel pump relay when it doesn't receive the Ne (engine RPM) signal from the distributor.

Code 52 is an open or short in the knock sensor circuit.

It sounds like the ignition had been switched on when a few connectors were not connected.

 

[Sigma]

I cranked it over with the distributer disconnected to build oil pressure, I then connected it and fired the engine for the first time.

What happens though, is that the engine light remains off until you blip the throttle to about 3k.

Have you reset the ECU and tried again?

Are you using a stock or a modified ECU?
