Although there is no guarantee, the most likely issue if there are NO other electrical types of 'gremlins' is that over time (both of my /88 Suburbans have over 300K miles on them, so that's a LOT of wiper activations!) the rotation of the wiper shaft has rubbed the insulation off of one or more of the wires in the harness to the point where rotating the arm creates a ground and kills the ignition. You might get lucky and be able to fix it yourself if you're comfortable with the idea of tearing the column down, or you might be money ahead to bite the bullet and take it to a GOOD auto electrical shop, but if you have to go that route, take the time just for giggles and disconnect the wiper motor itself and see if it still happens. If it does continue, you know it's not the motor grounding, but unfortunately if it doesn't you can't be sure if it's the motor unless you place another motor in the circuit (including the ground to the chassis) in it's place.

It sounds like thw firing order's wrong, rotor might be positioned wrong, or the distributor is off a notch. The distributor cap might be 180 degrees off as well.

The 1990 Chevrolet Suburban has the most common hook-end wiper arms. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
