Thank you. I will recheck all the timing marks today. Ill post my results after I finish

OK, if the timing is correct, we will look further into this problem.

sorry, i have been sick and havent worked much on the car. I did check the timing and it was right on. i did set it ahead and behind a tooth. setting it 1 tooth back did make it run even worse. but forward didnt change it much at all. the history on the car i know is that it broke about a year ago. the owner said it just stopped and wouldnt do anything. prior to that it did have a new head and gasket put in. but nothing on the lower engine. it was supposedly ran out of oil cause of a stripped oil pan drain plug (which i replaced with another oil pan from wrecking yard). its sat in her driveway for about a year until i picked it up a few weeks ago. maybe gas is bad. im not sure where to go with it. it still gives me the code 0340 (cam position sensor). thanks, i appriciate your help on this project.

I must apologise my self, i am on leave just now and i have just popped into an Internet cafe to check my Emails, i will be back on line full time next week, i don't have any information on hand to work with just now.

Hi Bill,

I am back at home now, can you give me an up date as to where your at with this problem?

mark.

hey Mark, I hope you enjoyed your time away. As far as the car, I haven't done much with it since the timing. I did find out that the gas in the tank has been sitting for about a year or a little more. Don't know if that could cause it to have no power. It seems like it lacks power when I push on the gas. At idle it sounds really good. Still have the code 0340 (cam position sensor). Compression is right at 150 on all 4 cylinders. Transmission fluid is full and oil is good. If u need any more info, let me know. Thanks again

HI Bill,

Had a great time, holidays are always way to short, but back to the salt mines we must head, lol..... OK, With the valve timing correct and a cam sensor indication still showing we may have a bad connection at the loom plug, maybe a corroded terminal or a loose pin, i would drain the stale fuel and flush the lines, replace the fuel filter and add a liberal dose of injector cleaner as well, go through these steps and get back to me with what you find, also don't disregard a faulty sensor if all checks are ok.
