Alright my car has been acting real weird as of late. Couple rough starts where it seems like it wants to die but doensn't Then about a week later does the same while driving near like 2k rpm kinda bog back and forth b/w like2k and 2400 maybe. For a while it was only while driving, until yesterday it did it at idle. So I took some TB/intake cleaner and pull the hose of my intake leading to the IACV and sprayed about half a can...the rode out that night with no symptoms. To be on safe side sprayed other half in the can today.
Well tonight it's extremely cold, and seemed like the cars idle change similar in the way the stock e fan cuts on after u sit for a while..however I don't think the fan was even on at the time.
So now I'm gonna replace cheap crap to try and narrow problem down like cap and rotor for distributor, and maybe the coolant temp sensor.
Read one post saying theres 2...one for gauge and one for ecu...my guess is the ecu is the one that affects engine operation and performance...or should I do both. Also do you have to drain coolant? It's located where the rad hose runs to right..just screw old out and screw new in?
Thanks for any help. Btw since the engine issues I've used gumout regane fuel cleaner, checked and cleaned top of spark plugs, and changed fuel filter (filter before the problems). Wires are fine, and also sprayed TB/intake cleaner i nthe IACV like I said.
