I have a 94 formula just put a new trans in it and drove it for about 30 minutes and the car started missing crackleing and backfiring any one know what might be wrong with it
I did the trans work and i never unhooked the O2 sensors all i did after the trans job was take the car to the car wash and hose of the motor and fill it up with gas and then the problems started
The other day i drove it and it cleared up and the got worse agiain The car is not throwing any engine codes so i just need some input on what to try to fix the problem
I can tell you for a fact that hosing off the engine will cause heartache in the near future. I did that with my 93 Z28 (LT1) and ended up replacing the optispark due to it shorting out. No engine light was thrown but the car ran like crap. If it continues try to pull the optispark and dry it out. Also, check the plu wires and coil to make sure that the water didn't short anything there. Good luck.
