Strange problems happening all at once
Hello everyone, recently my car has been having some really strange issues. It started with the security light coming on, which now stays solid while driving. Shortly after this happened it began stalling. It will start right back up, but then the idle will be really high. This also seems to affect the transmission operation, but only when it is acting up. I have already tried replacing the ecm as I read somewhere that it helped someone with similar issues. It did seem to help for a while, but now the problem has returned. I am at a loss for what to try next so any help would be appreciated.
