This morning I returned home from a 100 mile motorway journey. The last couple of miles were through town at 30 MPH. Stopped at a supermarket for SWMBO to collect groceries (say half-an-hour). The car was very reluctant to start and only did so when full throttle was applied and it was seriously down on power and wouldn't rev. It ticks over fine and doesn't misfire.
This is new territory for me. I suspect the problem's to do with heat soak, although I've never had any problems with the car.
I've had it eight years and it's now done 48K. I serviced it 4K ago (oil, filter, plugs and air filter) and not done anything since other than to occasionally check the oil (it doesn't use any). I last filled with petrol 200 miles ago and it's over half full.
I've no EML on, although it comes on with ignition and goes out when it (eventually ) runs. I suspect that means there's no codes stored?
Would a dodgy MAF throw up a code? TPS or stepper motor?
I'm also thinking fuel filter or even tank breather.
1. Remove petrol filler and replace to see if it's caused by a vacuum.
2. Remove air filter and check nothing's blocking the inlet.
3. Unplug MAF to see if it runs any differently.
4. Check TPS and stepper motor - can anyone tell me how please?
Anything else anyone can suggest?
I hope it's not the well publicised timing chain problem that afflicts these. I understand that produces an EML.
