I have an 86 california-emissions (yeah!) equipped K-5 with the L-code 350 and 700R4. Lately my truck has been acting up. Every once in a while, while I am driving, the check engine light blinks and the motor seems to cut out for a second. Then it goes back to normal. Anyone know what this may be? (crossfire in the ignition?????, distributor going bad????) Also, with the check engine light not staying on, does it still keep the code in the computer? I plan to buy a code reader but would like to know your opinions on what my problem might be. Thanks.
