Had the car mot'd on friday. They replaced the cat for the mot and a couple of new tyres.
Brought car home, fine. Took the car out for a spirited drive on saturday morning and she behaved perfectly, didnt miss a beat. Thought i would give her a wash before putting her back in the garage.
Got her out sunday morning to take her the 20 or so miles to the kit car show at stoneleigh. She was fine for about 15 miles then she started to have a very minor stutter. After a minute or so a warning light on the dash flashed a couple of times. (Having just checked the manual, it was the catalyst overheat warning light). I have never ever seen this light up before. She had a decat and has always been fine. Sometimes had her swapped back for mot's, but never a problem. Anyway, the stuttering stopped and the light went off for a couple of miles. Then it came back on, flashed a couple of times, then went to permanent on. As soon as this happened the car went into a sort of limp home mode, very lumpy running and wanting to stall. This just happened to coincide with the build up of traffic on the approach to the show. Nowhere to pull over and plenty of traffic We were so close to the entrance that i managed to keep her running and get into the show. Found the stand and parked her up.
We started her up a few minutes later. She started ok but as soon as i revved her slightly the light started to flash, then go solid and lumpy running again. I was hoping that water had got in somewhere when i washed her but thought it strange that she was ok when cold and damp but lumpy when warm.
Thought it would be wise to call out the breakdown people. He was confused. He tried his reader but it didnt want to talk to our car (obd2 and ours is obd1). Removed the spark plugs and they were fine. He didnt have a compresson tester in the van. Checked the oil and water (they looked fine to me). A couple of people there mentioned hgf, but having had this previously fixed i didnt think this was the likely cause. Breakdown man said he could recover me back home but as we were already there and had planned on camping we choose to be brought home today.
So she is back in my garage now. Most people seemed to think it was a faulty or failing sensor. She did have an occasional hesitation under acceleration before i sorn'd her, but i had put it down to not being used a lot and requireing a good service. I think it was connected now.
Could anyone point me in the right direction. Lamda springs to mind, but my mechanical ability is on par with a playskool host
