Re: engine stalling while driving....HELP

I had the same problem when first got my car. Replaced the fuel filter and spark plugs but it ended up being the igniter. Do you sometimes have problems with the car starting back up after it stalls?

Unless your timing was really off maybe. But I doubt it. I would check your o2 sensors. Tell us more about the motor. Did you just swap another 1.6 in? Also check your air intake track. When i first did my greddy kit using the stock intake, it blew the hose off the intake mainifold slightly where it looked normal, but my car would just stall when I would try to drive it.

it doesnt completely stall to where i have to start the car again. i overheated the motor last week and got my head rebuilt and replaced the water pump.thats about all i did. its nonturbo. i also got new wires. the car start right up thats why im rulling out timing and it idles great. my friend had this problem with his 240 and it ended up being the ignitor...so...keep the info comin...

Sounds like you need a 1.8 swap.

Check all of your grounds you may need to reset your timing since the ground was off the motor.

ymmv

Also, a minor idle correction may help aswell.. as we found out with ultimateforce's miata. His car was stalling due too low of an idle.

try what kung=fu said. you just had a rebuild head...check the brake booster hoses for vacuum leak from installation. it can also be early signs of stuck iacv...but it'll fluctuate uncontrollably with a consistant pulse...how about leaks along the intake piping?

don't rule out vacuum problems. they're cheaper to address first! and free to diagnose yourself.

good luck
