Tach jumping and engine stalling.

civicninja98 · #1 01-04-2005, 10:17 PM

I have a 98 civic Ex, d16y8, stick, with crane cam stage 2 cam, adjustable cam gear, underdrive pulleys, helix power tower, aftermarket headers, cat and exhaust redone all the way back. I only say this because i'm not for sure if the cam could be causing the problem, much less anything else, so I am looking for some ideas to solve this problem. When the car idles at normal operating temp, the tach will jump eratically, and the engine will not react to it, it will stay at normal idle. Then while running the car will eventually die. Driving the car is not possible, it will backfire and sputter and die. This happened before and it was a bad ground for the ecu on the thermostat housing. That was replaced and it is was doing fine. Now it is doing it again. I am pretty sure it is electrical with the tach jumping, but am looking for help. It has a new distributor on it as well. Any ideas? I greatly appreciate it.

sounds like an ignitor

try advancing your timing a degree or two

i recently had the iginitor replaced about 7 months ago, is it possible for it to be bad already? Could it also be the coil again?

from where? i have bad experience with aftermarket parts. Try sticking some O.E.M parts back in there.

the ignitor and coil came from honda. the only things i have on the ignition system that are not oem are pugs wires and plugs. i have 9mm wires and denso high heat iridiums. What do you recommend? Should I go ahead and put oem wires and plugs back in it?

WELL I THINK BAD GROUND CONNECTION COULD BE THE PROBLEM AGAIN.
ALSO NOT SURE IF YOURE USING OBD2 ECU, MAYBE ITS NOT COMPATIBLE WITH YOUR CRANE CAM TIMING. IF I WERE YOU ILL PUT THE OEM CAM BACK AND SEE WHAT HAPPENED.

Cool, thanks for the help everyone. It ended up being the ignitor. The terminal for the lead wire from the coil to the ignitor for the tach was fried. It was arching really bad and fried the terminal. So I replaced it, adjusted the timing 4* and it is running better. thanks again.
