First of all my car begain to run like crap then would die andnot crank up again until the next day.So i figured it was the opti and since I was in their id fix my timing cover seals they leaked bad-Anyhow i replaced the seal and bought a brand new water pump n all and i bought an opti with the msd cap and rotor,new wires,plugs bosch single platinum gap .050. installed it all correctly and nothing! the car rotates and pops and spudders out the exhaust. what i do wrong

 

Fuel? Start checking for leaky injectors, and the FPR for being broken. Maybe the pump is bad too. Get a fuel pressure gauge and check the pressure.

 

my pump is good has good pressure i should try a new coil would that help? also i have a broke sensor its under my intake has 4 wires goin into it wonder if thats a problem

 

Check the coil and ignition module and make sure the rotor is on correct and the opti is in it's correct slot or the splines or installed correct(93&94)

 

i would check for leaky injectors
but yeah that sensor u are talking about, i believe is the iac - idle air controller and that being gone will cause your car to run like crap

 

im gettin a new coil tomarrow mine is a 93 i didnt think their was a wrong way to install a rotor would it matter if i turned it 180degree and put it back on or what? i did notice that it went on alil to easy

 

Pull your #1 plug and bump it over with your finger in the hole till ya hear a woosh. Then look at which way the rotor is pointing. It won't run 180 out,but it will backfire big time.
Have that stuff checked before ya spend the money.


The original problem sounds like some unit was getting hot and not functioning so I would try to correct that problem also. I think something is off with the opti and the new rotor and cap is why it don't run and backfiring and the previous not starting is the coil or ignition module.
After fixing whatever is wrong disconnect the bat for 5 minutes to reset the computer. It will take it 50/100 miles of driving to relearn.
