When im accelerating the car wants to putt/sputter around 3000/4000 rpm, ive replaced ignition coil, tune up, timing adjusted, o2 sensor and lots more. It didnt start till it got real cold outside.. After i replaced the ignition coil it started to cut off on me. Left it idling and it shut off and when i was braking around 7mph it cut off. What would be your suggestion?
I think i received a defective wireset.

how are the spark plugs? or when did you change them last. plug wires should have 5000 ohms per foot if more than that they are defective.

Changed in march. Ive replaced a lot of parts, all with brand new parts. Everything has been done within a year.
Front struts, cooling fan switch, head gasket( had warped head-Milled), water pump, intake gasket, belts, thermostat, sparkplugs, wires, filters, ball joints, alignment, o2 sensor, ignition coil.
Now its shutting off on me, just cutting out, powers on, cars off????
AND still putting higher rpms??

scan for codes and check fuel pressure first with a gauge auto parts rent them. clean throttle plate on both sides and iac hole with choke cleaner and check for a vacuum leak. see link
