Whenever i put my blazer in gear it dies

IAC sensor.

Camshaft position sensor causing random misfire. Stuck EGR valve or clogged EGR ports.

Please comment on my info.

you have a bad fuel pressure regulator. it control the the fuel pressure in the rail.

COULD BE A WEAK FUEL PUMP

I would start with the rotor and cap. I just worked on one and it was the distributor was bad.

If you need to remove it and rplace it heres how.

Distributor Removal and Installation REMOVAL

1. Remove bolt holding air inlet resonator to intake manifold.
2. Loosen clamps holding air cleaner cover to air cleaner housing.
3. Remove PCV make-up air hose from air inlet tube.
4. Loosen hose clamp at throttle body.
5. Remove air inlet tube, resonator and air cleaner cover.
6. Remove EGR tube.
7. Remove spark plug cables from distributor cap.
8. Loosen distributor cap hold-down screws and remove cap.
9. Mark rotor position for installation reference, then remove rotor.
10. Remove two harness connectors from distributor.
11. Remove two sets of distributor hold-down nuts and washers from studs.
12. Remove bolt and spark plug cable mounting bracket from top of distributor housing.
13. Remove bolt and transaxle dipstick tube.
14. Carefully remove distributor from engine.

INSTALLATION

1. Install rotor on shaft.
2. Position distributor in engine and ensure O-ring is properly seated on distributor. Replace O-ring if it is cracked or nicked.
3. Carefully engage distributor drive with slotted end of camshaft. When the distributor is installed properly, the rotor will be in line with previously marked line on air intake plenum.
4. If engine was cranked while distributor was removed, establish proper relationship between distributor shaft and No. 1 piston position as follows:

1. Rotate crankshaft until number one piston is at top of compression stroke.
2. Rotate rotor to No. 1 rotor terminal.
3. Lower distributor into opening, engaging distributor drive with drive on camshaft. With distributor fully seated on engine, rotor should be under No. 1 terminal.

1. Install distributor hold-down washers and nuts. Torque to 9 ft-lbs .
2. Install spark plug cable bracket.
3. Install two harness connectors to distributor.
4. Install distributor cap.
5. Install transaxle dipstick tube.
6. Install EGR tube to intake manifold. Torque bolts to 8 ft-lbs .

I WOULD CHECK IGNITION FUSE TO SEE IF POWER GOING TO COILS AND IGNITION MODULE. REPLACE DISTRIBUTOR CAP AND ROTOR.HAVE IGNITION TIMING CHECK.DISTRIBUTOR CAN SLOWLY WORK A LOOSE JUST A LITTLE TO THROW OFF IGNITION TIMING SO PLUGS WONT GET NO SPARK.

check for minor vacuum leak and map sensor,pcv,egr valve

check idle speed spark plugs and wires. vacuum leaks fuel pressure could be weak.

Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
