OK, here's my problem. Got a 2000 Focus se 2.0 zetec.
At start up the engine is cool it runs great for about a minute, then while idiling the engine starts to lope and run rough.
Has no codes set but still thought I would change the TPS but no change in running. I have changed the obvious like spark plugs, air filter, and fuel filter.
Compression is 180 to 200 psi on all cylinders.
I hooked my scanner up and data shows timing jumping from 25 to 35 degrees. I am not sure this is a true reading because the ingine idiling is not constant.
Could timing belt have maybe jumped a tooth or two?
I am pretty sure the fuel injectors are doing their thing by listening to them through stehoscope but could be wrong.
So far I have only spent about seventy bucks on parts but I really hate to go much further until I have a better idea of whats going on so I was hoping someone else may have been here before.
I read a lot of the post here but haven't found any yet that match my problem but I am still going through them.
I appreciate any thoughts or suggestions
Thanks
Also fuel pressure is 38 to 39 psi.
