Egr vacum solenoid

[89ranger2.3]

Can the egr vacum solenoid cause the engine to run rough at idle but run fine driving its on a 89 ranger 2.3 5spd

 

[BRUTUS_T_HOG]

sure, but not likely.

codes or something? one thing that DOES happen though is there is a small air filter in the bottom of it. that usually rots away and allows too much air in. i stuff an ear plug down the hole to act as a filter. code went away. also make sure the vacuum lines are not backwards

 

[89ranger2.3]

when your looking at it is it inside where that spring is and my vacum lines are green on top and red on bottom

 

[BRUTUS_T_HOG]

its on the bottom. a circular cap that you can carefully pop off with a screwdriver. i had to unbolt it front the fender to gain access

 

[89ranger2.3]

where the vacum lines go into it or that white cap on it

 

[BRUTUS_T_HOG]

white cap, but what are your symptoms and problems? a rough idle with ok driving sounds like a vacuum leak

 

[89ranger2.3]

when it idles it sounds like a v8 does with a big cam but driving its fine

 

[BRUTUS_T_HOG]

can you hear any air hissing or sucking sounds? start checking all the vacuum lines especially the brake booster and the pcv valve. check over the entire intake manifold.

does it do this when warm or cold?

 

[89ranger2.3]

all the time and yea i can i jus put a new grommet in the brake booster

ok you need to find that vacuum leak. just poke your ear around to guide you to it. you can also take a spray bottle of water and spray around spots to see if the noise changes or makes a slurping noise.

starting fluid or propane will smooth out the engine when you find the leak but in my experience starting fluid doesn't last long enough and not everyone has a small canister of propane set up with a long hose on it

 

[89ranger2.3]

ok i appreciate it

the info about the hissing would have been great to put in your other thread about this problem.

 

[89ranger2.3]

yea but i still have it after ive replaced all the vacum lines so i was wondering will this solenoid interchange with another ford car or truck

 

[BRUTUS_T_HOG]

the quickest test to see if this solenoid will even help. unplug the red and green hoses AT the intake manifold and plug those ports up. honestly hoses that small won't cause a significant running problem. you have a large vacuum leak that is causing it to run rough
