172 cup.
Was running fine and after being sat on the drive for about 3 to 4 weeks it developed a missfire.
It had new OEM leads and new ngk laser plat plugs.
Eml flashing and then solid, stinks a bit.
I pulled 2 of the injectors and found them to be a bit dodgy so replaced them
Obd brings...
I plugged 3 on to injector 2 and it ran. I only used to gauge if it was firing the pot, but then disconnecting it to see if there was any change in behaviour
I switched the harnesses over between injectors and the wiring it fine.. might just be a coil pack, dodgy lead or plug or something.
Just a funny one with there being 2 separate faults at the same time
I changed plugs for ngk and fitted new OEM leads and car was running fine.
Parked up and just fired it up to go for a drive and it was misfiring from the outset with engine light flashing and going constant. Plugged in my obd and got 300 random/multiple missfire.
Unplugged injectors one by one...
My garage called to tell me that one of the pipes on my cup has a small leak as the heatshield from the exhaust has rubbed a hole in to to.
First question, without being there to see it which hose would this be? Also is this pipe cup specific?
I was thinking it would just be straightforward but having done a search it seems I have a few things to think about, airbags, horns, steering wheel angle sensors etc?
Anybody shed some light to make sure I’m not getting mixed up and don’t buy the wrong bits :)
Hi all,
Just bought a cup which came with this exhaust. It’s not to my liking so I’m going to sell it, but I don’t know what it is. It’s a cat back though. Any ideas?
Which wires did you play with near the fuse box by any chance? I had an issue like that a while ago and it was dirt connections at the fuel pump/injection relay.
My cup has just randomly developed a misfire and wondering where to start really. A while back it cut out and wouldn't restart which turned out to be dirty connections at the 5 pin relay which I sorted and has been fine since. It's also had a new TDC sensor and the plugs were changed 15k ago...
I've read a couple of posts which say just get them from any motor factors, having been to 3 who all say dealer part only (who want £20 for it) where can I find this? A relay should only be a couple of quid!
It's a 172 cup..
New coil pack installed - no difference. Euro car parts also gave me the wrong (old style) tdc sensor and mine has the blue connector so need to get from Renault and try that. I can hear the fuel pump prime as well. I've pulled the 3 black relays and cleaned them up too.. Any other suggestions...
