Resolved 1G Bogging in first and second

[4g63laser]

Basically the car starts and idles good... but sometimes when i start moving in second gear and the rpm's are between 1500-3000 it will bog down and literally throw me around the car. same goes with going into second and cruising in third (rare)

this has been going on for about a week and now today my engine light came on everytime it bogged but then went away.

i didnt drive it much this winter so i put in new gas and fuel injector cleaner... but nothing has worked. what could this be?

my one battery terminal connector comes off easily could this be a problem?

tighten your battery terminal and do a tune up(plugs,wires,fuel and air filter)

I agree with him tighten the batter terminal, Also check your Coil. You can take them to Autozone to have them tested.

Ok my engine light comes on and this sensor goes from the 100's to 0. when i let off the clutch my car bogs like crazy until the numbers go back to normal. it keepos doing this while i am driving as well.

what could this be?

Did you set up the AFC Correctly? Make sure to follow the directions to the T on setting it up otherwise the car will run like crap. It sounds like you picked the wrong option in setup. You can access it and change it without redoing everything else from the settings option.

Its been a while, I hope that helps you out.

Sound like you keep loosing the signal from the MAF. The Karman count is the airflow signal from the MAF that the SAFC modifies and feeds to the ECU.

Make sure the wiring is good.

mmmm thats weird, the safc has been installed for 2 years now without any problems.

What's weird about stuff breaking?

It's not clear from your post what happens first so that's my best guess based on what you've provided. Usually the SAFC read 3Hz even with the engine not running so for it to read 0 is suspect.

sorry i meant 3 i should have been more specific.

so it will be idling good then boom, it goes to 3 and misfires, same when driving. and when it goes to normal the car runs good.

I took it to a shop today and they said im missing pieces from my ignition coils. wtf this is driving me crazy, i have buschur racing coils and it ran fine for a year with them... now they are just missing parts.

could it be loose wires causing this problem?

Problem was a bad ground in the ignition, and a messed up wire in the maf, thnx for your help steve.
