Technican: check transmission fluid levelif ok then
sounds like you have a vacume leak at the transmission vacume line or the vac swit itself First off pull the line off of the intake and cap off the connector then put the car in gear
If that does not solve the problem check for other vacume leaks aroun engine throttle body an make sure all your connections to sensors are solid
Technican: Hello
Were you able to take care of that problem?
did and were you able to use my advise?
do you still need more info?
I would like to know the outcome
thanks
Owner: no, fluid is ok, vac lines ok, there are no vac lines leading to this trans that i can see only a vent line and this is ok, electric connection ok on sensores still runs rough
Technican: ok lets take a new approach
first check for spark at each wire end with a good spark plug to make sure all is firing well
then remove one spark plug at a time and see if there is a significant change in the engine idle
and check for vacume leaks ariound the intake manifold then get back with me
Owner: have check spark is ok no vac leak, the car has 281000 miles on it could it be loose timeing chaine, burnt valve, wore came shaft or lifters
Technican: yes check the timing to see if it is off the chain is more than likely gone with the amount of miles you have on it
did you have a vale job done when you replaced the head?
the cam should be good for 500, 000 mileslifters are a possibility also and is cheap insurance if the heads had to be pulled anyway Here's How To Get Guaranteed Solutions In Minutes
