ok yotatech i need your help bad... this is my daily driver im going to walk to work tomorrow morning..... ok so here it goes i got off work today came on like normal lately at idle while cold my truck idles a little low so i let it warm up slightly while i locked up from work and came home drove great and parked her in the drive way... then about 2 hours after i came home i started my truck and it would idle really low then go up to normal idle then drop low then it would like pulse rev up and down up and down but very roughly.. at first i was thinkin miss fire caz when i would rev up ever so slightly and hold it at a certain RPM it would pop and back fire... idk what made me check my oil but it was low so i grabbed the last quart i had and threw it in there started it back up it ran for a little while rough like i just explained then backfired loud and then idle smooth.... then i started to drive it and 1st gear no problem but in 2nd gear i dont have a tac so around i guessing 2000 or 3000 rpm it would like retard out like and bounce and pop and jolt the whole truck around then would be fine until 5000rpm... and so i limped it home and heading home my engine light would blink 5 times then 6 then 3 then 2 long times then 3 again then once so i borrowed my buddies truck and got spark plugs oil oil filter im going to do all this tomorrow but if any know what else could be wrong plz plz help me out thank you very much guys

 

i know the discription is long but i wanted to give as much info as i could i really need her up and running asap or ill be walking until its fixed i blew my prelude up about 6 months ago so rebuilding that so i need my truck to drive ughgh i hate electric problems i hope its simple..

 

u need to count the number of engine light flashes in the correct order, the order u have them now there are no codes by that number

 

but it sounds like u have a problem with your airflow meter, try to get the codes in the correct sequence

 

yea i havent jumped the ecu yet to get a code im going to replace the plugs today and oil change and if that dont fix then ill get a new cap rotor and plug wires.. ill try and get a stray wire and jump the ecu to get a code for you guys.. do you know where the little clip is that i do that i have a 93 extended cab v6 if that helps at all..

 

if anyone has any other suggestions other than plugs wires oil change and cap and rotor and plug wires please let me know

 

ok so i let it idle and it will pulse up and down and idle low and rough and then stall then i will here a really rapid ticking sound in the passenger side like on the fire wall??? i have no idea what that is.... any info on that one?

 

Clicking is likely the Circuit Opening relay turning on and off and that is controlled by the Fp contact in the Air Flow Meter. Would check the AFM out:

And the fuel pump test jumper would be a good way to confirm the AFM is dropping the CO relay out:

ok ill check both tonight thanks!!

 

ok so i switched out my mass air flow sensor out and put in my old intake set up and it idled a little smoother but still blinking engine light ugh this sucks need to get a diagnosis for the problem

 

Pull the trouble codes and we can help you from there, with out the codes were just guessing at what the problem is.

 

make sure u have no air leaks between the afm and throttle body, also check for any vacuum leaks

 

no vacuum leaks and no air intake leaks.. myyota: how / where would i get the trouble codes? if there a plug i can take a paper clip and connect it and count the flash like the older hondas?. if so where is that plug located..

 

Passenger side off the side of the fuse box under the hood.

If looking at it from the front of the car you need to bridge these:

O O O
O X O
O O X

O O O
O O O

Think that's right, lol. Help me out if I'm wrong someone. Bridge those then turn the key and write the number in blinks in the order the appear.

 

That could be the order, krytellan, but I'd have to go out to my vehicle and compare.......which means I'd have to leave my coffee to get cold. Not good.

I'd just look under the diagnostic port cap for the label. Jump pins Te1 and E1.

 

The circuit open relay 4crawler refer's to is behind the pass. side kickpanel near the floorboard in the cab, if you go to actually look for it. Pinpoint where that clicking is coming from, though. That'll be a big clue. Because, if what you're hearing is actually the EFI main relay, the problem could be an intermittent voltage to the ECU......which might explain, to me, the seemingly odd behavior of your CEL. AFAIK, when the ECU displays a CEL while driving, it should just come on solid and not flash the way you describe it.

Anyway, find out.

 

i see a clip that says diagnosis but its different than what you put up its:

OOO
OOO
OOO

O O

OOO
OOO

 

There ya go.

 

ok cool thanks guys ill get the code as soon as i get home thanks for all the great help so far!!!

 

oh wow ok well now here is the deal.. just got a call from my uncle he just wrecked his 96 toyota tacoma he called and asked if the motor would fit into my truck no problem??? i have the 3.0 and he has the 3.4 how hard is it to swap the motors out? direct bolt in??
