after leaving the car for the weekend I started this week and got a misfire ... friend has obd and checked for me and got the following codes

P0305 Cylinder 5 Misfire Detected
P1622 MAP Cooling Control Circuit Electrical
P0102 Mass or Volume Air Flow Circuit Low Input

I have changed the spark plug ... still has the misfire .

Cash is real tight to send to a garage thanks to covid So Any advise on what I can do next would be appreciated .

How old is your battery & do you leave it on a smartcharger when it’s left alone?

Assuming battery voltage is all good I would start by swapping the coil pack from no.5 cyl with another one and see if the misfire moves with it. New coil packs are not expensive.
 
batterys about a yr old .... it barely does alot of miles but was perfectly fine last week .... got a friend coming shortly and were gonna swap the ignition coil with another and see if the misfire moves as he'll bring his obd with him ..... I'll keep you posted as Im not sure how one fault can add another 2 but gonna keep trying what advise is offered right now as a garage will have to be a last resort :(

Thanks that was one of the first things someone mentioned .... appreciate your input too !
 
Changed ignition coil from 5 with cylinder 4 and the misfire moved to 4 so looks like i'll be starting with changing the coil .... i'll let you all know if the other codes disappear once I've ordered/received and fitted it :thumbsup:
