getting aggravated...

99 civic built ls
s300-precision 1000cc high impedience with box.
i tore the harness all down and tucked it. soldered and shrink wrapped everything



i had s300 in a p28. car was running then would just shut off and started misfiring and hated to run. put the same s300 in a 1.5 computer and problem was gone for about 2 3 months. now i start the car. let it idle...then 5 min later just shuts off. cel comes on. no codes. wont start....then let it sit. start it up and the cel comes on but wont flash a code or come up on the laptop!!

why did this happen twice? resistor box tested good..

sounding like an injector driver issue....starting to get tired of this crap..any ideas?

I had the same problem on a 01 Saturn sl the collant temp sensor was going out and would not throw a code

not real familiar with the s300 but i have heard they have some kind of security setting. Might be something to look into.

really your injectors are high impendence? Because if so you no need resistor box and this can be your problem, running your saturated inj. at low
impendence ohms.

low imp 2-4 ohms
high imp 12-14 ohms

They would be running at an even higher resistance! Good call. Probably fried your ecu

no i said it backwards...solved the issue i resoldered my pins and now its fine. pretty weird
