I searched for this and I couldnt find what I needed. I have an 87 Rx7 with a stock 13b motor. When I got the car it ran pretty well. But then I started doing the basic tune ups on it, (oil change, spark plugs and wires, air filter and fuel filter), but after every time I worked on it it would flood. So I changed the fuel injectors. That solved the flooding problem. Now at idle it runs really rough and sometimes dies. I went thru all my tune ups and made sure they were done properly, and they were. I havent done a compression test that will be tomorrow.

Is there anything else that it could be?

If you replaced your primary injectors, that means you pulled the UIM. And, if you pulled the UIM, and she's not running like she was, that means you have a vac leak somewhere

Thanks for the idea. Ill check for that too.

Check the TPS......my 87 was doing the same thing.

It's very possible that when you replaced the fuel injectors you used the old bottom grommets and they are now leaking air. Or one of the injectors is in slightly crooked. Original grommets are soft and pliable. Old grommets are rock hard. Several people have written with a similar problem and it was the air leaking past the lower grommets. Most notable at idle and not so noticed at higher rpm.

I used new gromments. Thanks tho. Every idea helps. As for the TPS, not to sound like a newbie, how do you check that? And about how much do they go for?
