Had trouble with high idling so checked tps connection and voltage which was ok but found ecu(water temp sensor plug was so badly corroded that i had to change it. Now i have complete opposite, idle is fine at 800rpm but keeps dropping down to about 100rpm for a couple of secs rises for a few secs then drops again. Any of you clever people got any ideas
