So here's a video of it from startup, to operating temp.


In the first clip, is the startup. Big puffs of smoke, but later on when it reaches operating temps, it went away.

Now my first guess here is that it's my primary injectors. Reason being, is that when I would drive it, it would have hesitation issues all the way up to 3,800RPM. This is with gas pedal to the floor from first gear, then when it reaches 3.8k rpm (which I know is when the secondary injectors kick in), it would floor it to red line with no problem.

I didn't smell any sweetness from the exhaust at all. Just average gas smell. My coolant overflow tank is about an inch over full, but it's been like that for quite a bit (I might have done that myself after changing water pump and putting too much coolant in).

So if anyone can confirm whether my suspicions are correct or not? Much appreciated!

 

Wow, that is rough. Check everything electrical and in the vacuum system. I would do a copression test and ignition system check first, probably. I have seen this before in a piston engine and it was electrical, at least in my Acura. Perhaps someone else has better advice? I would park this and not drive it at all.

Edit: check the throttle position sensor on the beginning too.

 

I adjust my TPS sensor not long ago to 1 ohm. I took out my primary injectors and lo and behold:


They do not look too hot. I'm going to send them in the be cleaned and hopefully that resolves my issue. The ECU ground was also in rough shape. Cut the eyelet off, and spliced on a new one while I'm in there.

is there anything else I should take care of while I'm in there?

 

just cleaned my primaries as well and replaced all the rubber vacuum hoses while I was in there and that did the trick for me, I was having similar issues and now it runs like a dream
