ok.. so after a shitload of problems with my vac. lines and my wga.. i finally got everything fixed!!

replaced vac lines
new wga

and my car seems to be running fine but when im accelerationg and let say im at 4000 rpms and i push in the clutch and hold it or shift to neutral.. the rpms drop down around 400-500!! is this normal or what???
 
Remember that the first line on the tach is the 500rpm mark, so you can't really see any rpms lower than 500rpms.

well it never really goes under 500.. i think.. ive only had it back for like 2 days.. not even 10 minutes from getting it from the dealership i gotta speeding ticked.. so im just not even paying attention then and just drove like a mile to work and back.. no where else.. but im just wondering wats normal

700-800 is about where mine sits when it is fully warmed up.


mine was at that when it was broken and now its at like 1000.. but then after driving for a bit itll be at 700 or 800.. and when i drive and hold in the clutch after shifting a lower gear the rpms drop to like 500 or so and go back up.. is that normal or what?
 
Yeah that all sounds pretty normal to me. Maybe when I wake up something will come to me but from what you've said it pretty much sounds just like how my car idles in different situations.

but do the rpms drop like that??

might be due to running rich and/or a possible slight vacuum leak

he said he just had all his vac lines replaced...

sounds pretty normal to me. Mine does the same thing as well. Sounds like you are coming off boost too quickly... if youre in boost and put the clutch in and do nothing else, its going to drop rpms lower than normal and jump back up.

mine would do that pretty badly before my WGA replacement, now it doesn't really do it at all.

ok.. so heres whats going on.. now that i finally gotta go for a real drive in my car this morning!! when im in a low gear... 2 or 3!! and i accelerate and shift to n! the rpms drop down to like 500 or sometimes to 0 and it shoots back up quick (which doesnt sound too normal)!! but when im in 5 and accelerate and shift to n they drop down no lower then 800.. is this normal???

ps.. sorry for keep asking and stuff and being a worry wart!! lol.. but i just got my car back from mazda and my wga was just replaced and new vac hoses.. and now im just needing to know if its ok.. or i needa take it back to mazda.. so thanks everyone
 
Mine drops below what I would call normal some times but never stalls..

Normally after running hard and then taking an offramp to a redlight.
