I was comming home last sunday in 88 TC motored bajabug, coasting down a hill and when I got to the bottom the motor was still running but I had no power. I pulled off and stopped and restarted the motor and limped on home at a best of about 30mph. I live at 6800 ft and it's been below freezing here and now it won't start. I cranks and coughs but will not keep running so I can't get it to operating temp.
I've checked everything I can think of;
fuel pump is putting out 75 psi
plugs are firing and are wet
pulled codes; 21, 24, 28
21 ECT checked out good, it's below freezing here
24 VAT I checked the temp leg of the vane air flow meter and w/o any values to go by, it changed resistance when heated w a blowdryer
28 also comes on below 50F
I checked the timing belt and it looked worn and loose and thought it could be the problem but I think the timing marks are lined up. The Haynes manual I bought says nothing about timing and the pictures they show of the timing marks are poor. So I think they are right but not sure. When cranking, my timing light shows about 20 degrees ATDC. That seems OK for startup in the cold but I don't know for sure. I've checked the TPS and ACT. Is there anything else to check?
