ECU, AIR TEMP SENSOR OR THE IGNITOR ON ThE COIL

[MaTTSuN]

these are the only things i have not changed or found to be working or not.

well no matter what i do i cant get this thing to make power under any load at all.

i can mess with the chopper wheel and get it to rev fine, a little rich but fine enuf to rev good and hard.

As soon as i put some load on it the thing sputters down and stalls out, the funny thing is i had it running and driving around town. It never had lots of power kinda ran like crap but it worked better than now

Now its just spits and pops and runs like crap under anyload

im rambling on so anything come to mind with this problem

it runs very rich the whole time also

when i unplug the CHTS the car dies so i figure it works....

 

im about a second away from dropping it off at a shop and taking it in the rear

I had the same problem. The car would strart, rev, but when I would try to drive it, or put it under load it would die. I changed my coil and that fixed it.

thats what was wroung in this video I made.

well im not running the Mega Squirt but i put a new coil in it befor and not much change

maybe the ignitor finaly gave up enuf just to idle but not give power.... does that sound right?

I'm thinking that the ignitor is the sort of thing that either works or not at all.

[MaTTSuN]

hmm then what would make it run ok then keep getting worse? it never made power but ive gotten it to rev well

once the load is on it boggs down

so you dont think its the ignitor?

how about the air temp sensor in the AFM? i unplugged that and it did nothing diff from what its been doing
