So i've been having this issue for a few months now and i cant seem to work out the solution so i thought i would type up in detaila ll the symtpoms.
- When i first start the car idels smoothly at around 1200 (i believe this is higher than normal?)
- car somtimes judders: exmaple today after 30 seconds of driving in first gear the car started juddering and the rpm went up and down between 1200-1500 when i put my foot on the clutch pedal it stopped until i lifted it back up then went away on its own.
- somtimes once i put my foot down the car takes a second or two before accelerating
- idles rough after a drive at just below 1000 rpm
- check engine light is on
I have ordered a PG 1 scan tool to see if what the engines codes are but the issues persisted before the check engine light appeared.
Only recently bought the car passed the MOT and had a new clutch fitted (came with a destroyed clutch) only driven twice (home and too MOT garage) before this so clutch may be related? Any help would be greatly appreciated. If i cant get this fixed might have to sell my car ;-;
Once you have the scan tool, please post the codes here. Otherwise we’d just be shooting in the dark.
- I assume that's one of those Chinese made MGS that they no longer make unfortunately no experience with those things cuz they never sold them in the US and they no longer make them anywhere. But to get a scanned and send me the code so I can analyze it
So i scanned the computer using my P Scan and got this:
Error Light On
2 error codes
stored codes
P0130 02 Sensor Circuit Malfuction (Bank 1 Sesnor 1)
P0170 Fuel Trim Malfunction (Bank 1)
Am i correct in thinking this is the Lambda sesnor in that pre cat in the manifold? The ZS has a MAP sensor not a O2 sensor in the intake i believe and i replaced the MAP sesnor recently.
Just wanted to make sure this is the case before i go out and order the part
