The Saga continues...more issues

[Jalisurr]

Hey folks,

So I recently discovered that, surprise surprise, the injectors on my car needed replacing. The guy I bought it from said they had been replaced with new Bosches, I guess those went bad too because I had two of them with ~6 Ohms.

So I pulled the plenum and installed all new Accel injectors, put it all back together and took it for a short test ride and it seemed great! Faster than ever and very smooth.

However, now, a week later I took it for a bit longer ride and it started running quite badly again. I was sitting in traffic for a little while at the start of the drive and then when I got to the highway on ramp and floored it it just stumbled and hesitated. Did a little more driving around then got scared and went home it was stumbling right off idle and also if I gave it any more than about 5% throttle.

Got it back to my garage and popped the hood, it smelled and felt really hot in there, and then I could hear what sounded like bubbling coming from the throttle body I think. I didn't see the coolant gauge go above probably 220ish, but I don't know.

When I did the plenum pull I only drained a little coolant, just enough to get it below the throttle body.

Looking for more of your infinite wisdom, coolant issues? Something leaking? Is it overheating and that's why it's running poorly? Or do you suspect something else and I'm barking up the wrong tree?
