my friend has 85 x-cab 4wd sr5 with a 22re he advanced the timing a little it runs much better now but now when u step on the brakes it idles up and down cause the idle is a little higher than it use to be is there any way to fix that with out going back to stock timing

olharleyman

check the idle adjustment screw I have the same issue and found it backs itself out and gives the up and down idle you speak of I think teflon tape on it will hold it where it needs to stay I will let you know in a day or two.

Elton

its screwed in all the way is there some wire he can disconnect or re route a vacuum line

Elton

anyone

srry man idk (keeping the thread alive)

the first thing i think of is a vacuum leak. the brake booster would by where id check first then all the lines. maybe double check the timing. idk just thinking outloud.

Elton

if you set the idle to high on a 22re it will do the same thing some sort of sensor or something im just wondering if theirs some way to fool it to think its right

taconasty

do you know what the idle is at? i mean timing, sorry. being a 85 xtra cab owner myself i wouldn't be suprised this could possibly a separate issue.

Elton

you no im not sure but the idle sits at around 1k what ever its set at it ripps now it sucked b4

taconasty

this may be a stupid question but does he still have the diagnostic plug shorted? i dont remember what its called the one in the engine bay you have to short out to set the timing.

Elton

wow you have to short something im sure it wasn't done the right way

taconasty

yep, check that and let us know what happens.

Elton

yea ill let him no thanks soo far

Elton

ok if we go back to stock setting what would be a good place to set the time with a header and full exhaust no cat

taconasty

i would put it at 5-6 degrees with the test jumper in. mine is at 6 maybe 7 and idles at about 800 and starts right up. no cat new exhaust and k&n drop in filter.

Elton

ahh yea he didn't use a gun had no clue about the jumper the poor thing prob has 10 degrees on it

mine was set at 0 with a carb and now its at 8 with EFI

Elton

update he never knew about the timing jumper and it was way the hell off its now set at stock but theres still something wrong with the idle it's like at 1200 with the screw all the way down
