hey ive been fighting these problems for about 3 months now at first the car would turn over right away and some times it would take 30 sec or so of cranking. i have a 3" cat back and high flow catco cat. so i changed the spark plugs it helped a lil i just reciently changed the cap and rotor it dosent have as much problems starting now as it did but it still dose some time. next the car revs how ever it wants to some times it idels normal and some times it drops down to 500 or 0 then cuts out.what could cause this. some times my car bogs down or shuts off as im going around a corner with alot of g's and some times it doesnt. is it possible all these problems are related. i hooked up a a/f ratio gauge in my car yesterday and it says its running rich as hell how would i lean out the ratio

 

check your timing. also make sure you maf isnt dirty that can make a car run rich.

Do you have a check engine light on?

 

i'd also check the starter, oil level and oil pressure. with harder g's there might not be enough oil in the pan to pick up. does it bog on down hill slopes too?

 

im going to clean my maf today. the starters been replaced twice once cause it went out the other because the flywheel ate it up.

the check engine light is on knock sensor malfunctioning, speed sensor malfunction, and 4 gear ratio incorrect.

i have oil and im going to check the timing when i clean out my maf
