My apologies. There are only a handful of Techs that take phone calls. Unfortunately, I am not one. If you'd like, we can continue here in Q&A chat and I can provide you with the information and help you need, and I can handle any follow-ups you may have. If you'd rather wait for a phone call, please standby until an available Tech can take your call.

sorry milege is 261,435

Thanks for holding!

Ok, the most common problem associated with the P1345 is a worn distributor. Remove the distributor cap and try to turn the rotor. If the rotor has play in it, the distributor is worn and will need to be replaced. This is actually extremely common on these engines. If the rotor has no play, then the timing chain will need to be inspected for any excessive free play. Like I say though, more times than not, the distributor assembly is the culprit here, especially with that high mileage. Please be kind enough to leave a rating for our Q&A using the 'stars' at the top of the page or click 'Accept' when I have answered all your questions. A 5-star rating is very much appreciated! Rating or accepting my answer does not cost you extra.
