Why's it running so rough??
 

I've put up with this problem way too long, and I need some help!!

When I start my car in the morning, it fires right up, and idles decent (for a 2.8 anyways https://www.thirdgen.org/messageforum3/smile.gif) When I plop it in drive and give it very light throttle, it bogs down, doesn't wanna move for a second or two, then fires right off and is normal all day! Any ideas why it does this? It never stalls...just bogs every time.

i think its normal...TomP responded before when i asked about it and he said to let the fuel pump go for a sec before u start the car (turn to on let the pump go then start it) it helped a bit

I agree with Graeme,
when i start my bird, i turn the engine to on first, you'll hear the fuel pump push gas to the engine, and after you here that stop, fire it up. Most engines will have a quick hesitation when first started anyway, think about it, it's their first time starting in hours.

I totally agree that it makes sense to let the pump run...but this is even after I let the car idle for up to 30 seconds sometimes. Shouldn't that give the fuel pump enough time to work properly?

My 2.8 does the same thing. When it's cold it'll start but if you don't gas it it'll die after about 3-5 secs. I have to restart it about 3 times before it'll idle. Mine has the hesitation when you put it in drive too. I'm gonna try the fuel pump thing w/ mine. I heard the 2.8's are bad for cold start hesitation anyway.

I've come to realize that I'm gonna have this car till it pukes for good, b/c I'll never be able to bring myself to sell it.
