Car is REALLY sluggish on first startup. Like it's loading up.
 

When i start the car after it's been sitting for a while it's really finicky, like it's loading up on fuel and needs to be gone to WOT to clean it out. It'll hesitate and accelerate like crap if I'm normally driving it. But as soon as I get it past 3k it's fine after that. It's weird, like an old carb setup. Every now and then I can feel a slight hesitation also.


I'm getting a MAF code, so I'm replacing it. Think that could be the cause?

Also, when I go to start it after it's been sitting for about 20-30 min, it barely comes to life or I'll have to crank for about 10 sec before it starts, both times I have to give it gas to get it to rev up. it'll idle at like 200 rpm otherwise.

Anyone? Bueller?

Oil pump get it checked out and please stop reving to build pressure! Sounds like oil pressure to me.

Oil pressure? I've got great oil pressure at all times.

How many miles on it? The restart problem sounds like leaky fuel injectors.

What does it do if it sits overnight? Does it fire quickly, or does it still take a long time to fire? I understand how it acts once its running.

If it sits over night it fires right up. I has new Lucas 30# injectors on it.

My vote is for leaking fuel injectors then.

They leak til pressure is bled off when you turn the car off, and the gas doesn't have time to evaporate if you try turning the car on too quickly, and it has a hard time starting. If it sits overnight, the leaked fuel evaporates, and the car starts right up.

Had the exact same problems on my '88 TA. Swapped the stock 80k/17-year-old injectors for some newer LT1 injectors at the time, and all was well :)

Hmm, I guess I'll try to get a set and see what it does.
