Thanx for the replies and support again. Yes hopefully I will have some good news tomorrow. The electrics is one thing I won't touch so the garages have dealt with that - can't believe all of the combined problems! frown The issues the past few weeks have been the most I've ever had in the 16 years I've owned her, prior to this she ran perfectly. I just want her back to normal. Does anyone know if any of these latest issues are linked to the problems / works done recently?

Well it sounds like the first garage were doing the electrical work without disconnecting the battery so to be honest, it’s hard to know what damage they could have done! BBR sound like they are a much better outfit and are getting on top of things so I’d stick with them if I was you.
P.S. I’d let BBR know about it so they will be aware that there might be electrical gremlins caused by shorts in the system from the previous garage.

Hi all, so the saga continues and am really fed up now. Am going to refer to both as garage 1 and garage 2 from now on. Collected my baby on Friday and was advised it was the ABS relay and that she had been taken for dirves along very bumpy roads and over pot holes to try and replicate the issue and dislodge the ABS pump / relay and coudn't, asked to be shown said relay so I know what to do and as the bonnet was raised I noticed #1 HT lead wasn't even connected to the spark plug, it was sitting about an inch above the cylinder head. This was pushed back in. Unfortunately garage 2 had no time to do the other works and I carried on my merry way. A bit of 'fluffing' as I like to call it and made it home ok. Garage 1 commented on the #1 HT lead not seating correctly so I'd already ordered another, albeit was a brand new set, however I was not told this until I commented that I'd found it like it when they were initially helping with issues. Replacement HT lead arrived on Sat and I swapped this out quickly before heading off again pushing it down very firmly. There was no movement, it was connected, but I didn't hear or feel any click in to place. Drove approx 20 miles, sat stationary at traffic lights and the flippin' over idling started again. Got to my destination but too dark to be able to check properly, a bit of fluffing again and made it home ok. Finally had the opportunity to check things over in daylight, HT leads 3 & 2 were the wrong way round in the coil pack. switched these around and finally got #1 lead to click on the spark plug, started her up and she happily idled at approx 800 RPM. Left her like this for a while and turned her off / on a few times and ok. Could still hear a bit of fluffing and when I covered the exhaust tail pipe she's farting like a trooper. I've read the leads can be switched and one on each coil pack is 'wasted', but all of this has caused so many problems the past few weeks. Both garages have now worked on the exhaust, sensors, ECU, electrics, spark plugs, HT leads, coil pack, window regulators and switches, air filter and housing - noticed this has holes in it - ABS pump and relay, I have never had so many issues, am I barking up the wrong tree or is some of this related to ongoing issues?? I feel as though I've been fobbed off and am not expected to notice certain things. I've spend good money after bad and am not getting anywhere. This has all stemmed from the original issue of the heat sensor breaking away from the CAT. I just want someone to sort this out and not stitch me up. Look foward to hearing from you.

It sounds like a whole load of issues but it also seems unlikely that they would all be caused by just knocking that sensor off the cat, however who knows what the garages have done in the meantime if they can't even get the HT leads back on correctly.

If you're still getting that fart noise I think you need to start by getting the car up on some wheel ramps and take a good look underneath and see what's under there that's damaged or leaking. I'm not sure what effect a big exhaust leak has on the way the engine runs on a mk1 but it's probably not helping.

Don't give up , it's bound to be a simple fix as they are pretty simple cars smile

Thank you JimSuperSix ;-) Don't worry am not giving up, I need her sorting, and yes, I bet it's something simple. Good news is that after sorting the leads out she drove almost perfectly today, bar the farting ;-)

Took her to another garage and they found that the CAT to front pipe flange was broken and that's why I am still having issues and can hear the exhaust, just unbelievable. Fixed and now running as should be.

Thank you all!
