i know you replaced the bulb, check inside bulb socket to see if the contacts are good, they can get coroded and make the flashing system behave oddly. you can use some spray wire cleaner but i usually wind up using fine sand paper folding it up and gently rubbing inside contacts. if this doesnt work and all other bulds are good (check those filaments), then you may be stuck checking wires for breaks in the casing or rusted points on outside of wires. hope this helps.

89 Has EFI not carb. I vote to give you a ZERO!! The problem is more likely the IDLE AIR CONTROL VALVE (no sh!@#) "IDLE"????

Hello, Check other Vacuum lines for leaks. If you have a 4x4, they can have Vacuum operated hubs and a leak anywhere will draw down the Vacuum. I found most pumps running at about 21psi. Check for a Vacuum Reservoir. The older models used one looking like a coffee can and they would rust on the bottom and leak.

If you take off a vacuum line and use a hand vacuum pump, you should easily find a leak on one of the remote lines. Another test idea is to remove the Vacuum pump lines, put in soapy water, and pressurize with about 3 PSI. Any vacuum leaks will blow bubbles and soapy fluid. Its your choice on what to do. I would reserve the soapy water for a line I find to leak with a hand Vacuum pump.

Many of the people wih your problem replaced the vacuum pump and were good to go. But if you can measure the vacuum and find the leak, you may save money on a part you do not need.

First . take off your panel that covers the fuse panel by your knees. put your head up under the dash and look for the shift linkage. some times the screws that hold the plate on where the linkage attaches break off. second things that go bad are the two plasic bushing that the shifter rod is held down by get worn out. Everything you need is a dealer only Item. If you get into and need help. Call me at 570-878-5222 Its a real easy fix if you know what your doing. The only tools you will need are....#30 torx socket, straight pick, phillips screwdriver, small prybar or a large flat screwdriver.

Sounds like hose got dislodged. Check under dash & fix. (If you can even get a hand in that area)

try replacing the injector driver module, or idm for short and this should fix your problem.
