ive got a 91 240 and when im going down the road it starts to hesitate then it progresses to not reving past 2500 and when i go to stop it wont idle and stalls if i dont keep the revs up. i have not a clue whats going on. when i shut off the car and start it back up most of the time it runs fine for a while. so any help would be great

IACV . . check it
check your plug gap
backfiring ?
AIV still in there ?
hold old are your plugs and wires ?
how's your 02 sensor ?

well ive romoved the aiv pluged all the lines for it brand new plugs and wires o2 sensor was put in right before i got it 4 weeks ago. it does backfire every once in a while the problem just got worse too. no it will not idle dies after about 1 minute

unplug you mafs then plug it back in and make sure its plugged up all the way and if is still does it then look and see if the top is bent badly and if any wires are showing. mine was doing the same thing and it was because when i was shutting my hood it was knocking the plug for my mafs out of place.

well i think its my maf now because i unpluged it while running nothing changed and i took it completly off the intake and it didnt stall out when it should have

s13_peacekeeper

it will run in a "safe mode" (the safe mode is not letting rev over 2,500rpm's.) just take it off, smack the maf a couple of times and then plug it back in. if it still doesnt work try reflashing your ecu.(just unplug the battery for a couple of min.) try that and let me know what happens....good luck!

honda_killer

ill try that
i also cleaned it out with electronic parts cleaner

still nothing going on with the maf it dont seem to be doing anything it dont die trying to idle anymore for some reason it stoped doing that about 4 messages ago haha

s13_peacekeeper

if it still doesnt rev over 2500rpm's then you might need a new mafs. if you have a buddy with a 91-94 ask if you can switch just to see what happens. usually what your explaining has somthing to do with the mafs. were is it idleing at now?

honda_killer

i do have a friend with a 91 so im getting his tomorrow to see if it fixes the problem so ill let you know then but it seems to be idleing fine now for some reason. no check engine lights either

s13_peacekeeper

is it letting you rev past 2500rpm's now?

honda_killer

he totally forgot to bring the maf home so now i got to wait until tomorrow

honda_killer

i got my mafs toady put it on and bam it runs srong once again

s13_peacekeeper

yay...good job! glad you fixed it!
