Problems After Engine Swap

[Pob 1]

Hi all,

 

I've just finished swapping the engine on my 1.9, it starts ok but it runs very lumpy, I've checked the cam timing and thats fine. It misses at idle and higher revs.... Any ideas? I carn't see anything I've left unplugged

 

Also my oil pressure gauge goes straight to max, it was fine before I removed the engine

 

Thanks,

Dan

For the gauge check that you've got the gauge sender and warning light switch connected the right way round.

I'll check that again, they are labelled... but I'll check

 

Could it be the fuel? It's been in there around 8-9 months

 

Thanks,

That's the gauge sorted.... some tool labelled it up wrong, Thanks Ryan

Do you know for sure the engine you have fitted was a 'good un'?

I don't see why it wouldn't be, the head gasket was replaced inc skim. Starts ok, just runs a little iffy. What could cause bad running if the engine had a problem?

Check plugs/leads/injectors

 

I have known a few people that have had issues like this that turn out to be pins simply coming loose inside their plugs. I had a loose pin in an afm plug after a putting an engine in. Wasn't the easiest of things to spot!

I'll recheck connections tomorrow..... could fuel be to blame? It has been in there a fair while and it's on reserve, what would be the best way to get it out?

You could simply remove the fuel line from the injector rail and run the pump.

 

However I doubt the age of the fuel will be giving you an issue, but if the level is drastically low I would get some more stuck in it.

ECU temp sensor/AFM/plugs/leads/dist cap/rotar arm/dizzy advance

 

thats what you should check, doesnt have to be that order!

Thanks for the info, I'll have a look tomorrow. The only thing that is not from the original engine is the ECU temp sensor... it wouldn't cause that much of an issue would it?

 

Thanks,

ECU water temp senders have been known to be the cause (and simple fix) of a lot of problems. Easy to do a one-for-one and eliminate it anyway. I'd try it.

I've got a few senders to try so I'll give it ago... Are ECU temp senders always blue? or this dependant on manufacture? The one fitted is black.... The others I have are blue

 

Thanks again,

Dan

high idle and misfire makes it sound like an air leak (vacuum) to me

My gti ran like a bag of crap after sitting for a year with very low fuel on the first start up. Good shot of injector cleaner and some V-Power cured it, worth trying the simple things first.

Sorted, not entirely sure what it was but I put 5 litres of fuel in, disconected the injector connectors and reconnected them, one of them wasnt quite clipped in. Checked the HT leads and it runs fine now

 

Thanks all,

Dan
