Not wanting to start, surging, both intermittently
Not wanting to start, surging, both intermittently i'll drive my car to work, mall, where ever, and when i try to start it sometimes (more regularly of late) it doesn't want to start, i'll have to try to crank it for 5-10 minutes, then when it does start, it barely does, runs bad for a couple of seconds and then using the gas pedal i can coax it to get out of its slump, and it will run fine. also, at times, if it doesn't do that, i'll be driving and it will start to surge. i'm trying to scan it for codes, but my scanner won't link to the car (another thread in pcm/diag). so, does this sound familiar? plugs/wires, maf, o2's, cps? i've replaced the iac and the tps and the plugs about 18k miles ago.
Thanks,
Josh

Clean the MAF lately?
Crank Shaft Position sensor can cause all of those problems...and it may not ever show a SES light. Mine didn't.
Plugs could be dirty and after it runs for a little bit they get cleaned off of the crud build-up and than can run smoothly.
Clogged fuel filter?
Clogged fuel injectors?
Bad/failing 02's can cause this too, and they will NOT always give you a SES light either. Mine were bad and I had no SES light, but the scan showed they were not working.

the surging just happened again, i was stopped and the engine freaked out and went to 2k rpms and then i put it in gear and drove and when i tried to accelerate, it would surge like gas wasn't getting to the engine. of course i realize that sensors could cause this, i was just using that to explain what it felt like.

got autozone to scan it, and i got the following:
P0128 - ECT
P0135 - O2; Bank 1 sensor 1
P0140 - O2; Bank 1 sensor 2
P0155 - O2; Bank 2 sensor 1
P0160 - O2; Bank 2 sensor 2
i have p0140/p0160 because i didn't use o2 sims for my headers, but i guess i need a new ect and front o2's.
thanks for your help

Do yourself a favor and DO NOT buy the Bosch 02's. Get genuine AC Delco 02 sensors. www.rockauto.com sells them for $74.00 each, less than the dealership.
