Okay, so before I get flammed, I'm simply asking for other opinions before I go throwing money at a Mazda dealer or a rebuild.
About two months ago, I was having trouble with hot starts RARELY. Typically after a fill up. It would take ~1-1.5seconds to start, the rare bad occasion a full 2.5 seconds. Typical reasons obv.. Compression, coils, plugs... so on.
I checked out my coils a month ago.. They were bad (white dots/thumb print looks) so I went ahead and changed coils/plugs/wires. Great!
So lately, cold starts are fine. 1-1.5 seconds as usual. I've noticed once or twice at school that when starting from a cold start, the coolant light would flash for a couple seconds as the car started and the rpms would shoot to 3k and as it warmed up go back down, coolant light would go back off.
Last night, after filling up had another pretty rough hot start. 2.5 seconds which seemed as if it barely wanted to start and for the first time coolant light flashed while hot. Lasted about 3-4 seconds and went back off.
When hot, I have also notice at lights that the cars rpms stay ~1k, but will dip to around 850rpm and the car shakes. Can definitely see it in the hood, but it quickly goes back to 1k.
I have also had only once (recently), where I have pulled up to a light and the rpms dipped so low the car died, however fired back up as if nothing ever happened.
After researching, I've seen that this is most likely compression. Possible vacuum leak. Not coils/plugs/wires since those are done. I've also seen where it could be the coolant seals since the coolant light is flashing when starting.
So with the shaking, I would assume vacuum leak possibly. Hot starts I would assume compression.
However the kicker for me is that when on the roads with three other Rx8s, I seem to have the most power. If we line up and take off from lets say, 30mph I seem to have no problem with inching forward slightly. (all of our cars having equal mods to exhaust only) So if all the cars were equal and I was displaying good power through all gears and rpms wouldn't that show healthy compression??
I'm lost with all of this and before I go spending money trying to figure all of this out I ask for some other opinions/things to look for to help me out. Would seafoaming the engine help any? I just started reading up on it and began to wonder if that would help find any vacuum leaks.
Thanks Guys!:Peace:
