I agree with everything you said and in the back of mind i have been thinking of how much i want to keep spending on the car to keep it running. I am going to replace both the solenoids. The sparks plugs he wrote on the repair sheet was that he replace the spark plugs with autolite brand. I will ask him if the plugs he used were factory recommended and how much would it cost to replace the plugs with the recommended ones. Overall the car runs well i am just getting really bad gas mileage otherwise i could put up with the slight puttering. But i thought it was just going to be a simple replacement of the plugs, if he didn't put NGK plugs would that cause the error P1526 and maybe i wouldn't need the solenoids replaced?
Ken you have put my mind at ease thank you![/b]
1526 is not related to the wrong plugs. the autolite plugs are the wrong gap(1.1mm, should be .7-.8mm. if they cannot convert metric to inches, you need to not go there). and, if the plugs are not common copper or nickel core, then they cannot be regapped(if they DID put copper or nickel core plugs in there, you need to go somewhere else). he might think they can be, but every plug manufacturer does not recommend regapping a plug with a precious metals tip(precious metals tip is like platinum, gold palladium, iridium, amongst others). beware of the "mechanics" who tell you they have been working on cars for 30 years, etc, because they might be set in their ways, and cannot cope with the new changes in automotive technology.
1526 although specifies the solenoid, and in a lot of cases it is, but the entire circuit that the vent solenoid is on should be inspected. realistically, the entire system of vacuum lines should be inspected. this is a labor intensive job, lots of stuff has to come off. the shop will lose money on this. you should first get an estimate on how much, then decide if it is worth it. i would expect at least 3 hours, if the estimate is less, they dont know what they are in for, and you might want to reconsider who works on your car. but i would at least start with getting the proper spark plugs in there. a few pieces that have to come off to get to the plugs also have to come off to get to the vacuum lines and tees. bottom line here is that very few "mechanics" out there have any experience with your car, and you are basically paying them to learn how to do things. most places will consult a flat rate guide and go by that. in the case of your car, the flat rates are usually not near enough, so if the job cannot be done in the quoted time, then they start looking for short cuts, or ignoring certain steps that are critical to completing the job correctly. it is going to get more expensive from here on, you might want to consider getting a different car.
