Question about 1998 Chevrolet Astro

Throttle body sensor

How do I replace the throttle body sensor on my van, and could this be the cause of the misfire of cyclinder # 5.? Both were discovered after the engine started running rough, and the service engine soon light was flashing. those problems were discovered by a computer connected to my van. I pulled the engine cover off, and I am mechanically inclined, but the access to the plugs still looks next to impossible. I cannot afford a mechanic unless I really have to.

Not for one cyl misfire. Not tobe hurtfull but if you can not afford a mechanic how can you afford gas, insurance etc. Get real here. The money issues are you r problem. You didn't like what was probably free and helpfull advice from a repair shop. You can replace the TPS but you need to put a volt meter or scope on it to confirm an issue. Don't throw parts at it until you understand the system your working on and its sensors etc. Everyone needs to find a good repair shop before you need one. Just like we all have a good doctor. don't drive all your vehicles until you only do break down repairs.

    Dont listen to this *******. I understand times are hard. He is probably a shop owner or worker trying to rip hard working individuals off. He isnt anyone to judge on affording mechanics. Go through and check some of your vacume lines before throwing any other parts or money at it. That is if you have already checked plugs wires cap and rotor first.

I have an Astro van 2003 and need to know where the air mass sensor is located.


The MAF sensor is located in the air snorkel in between the throttle body and the throttle body. A 5/16" socket is all that is needed to replace it.

P0302 is a number 2 cylinder misfire code. It has nothing to do with the MAF sensor.

Reving problems


The high rev sounds like a vaccumm problem. What year is the vehicle? If its
newer than 1995 it more than likely has a lot of vaccumm operated parts. I would check for leaks and get that out of the way.

I have a 1996 chevy express conversion van 5.7 liter I have misfire in all cylinder after the truck is warmed up I have new plugs cap rotor wires new o2 sensor. o2 sensor has been changed 3 times in 3...


No, the catalytic convertor does NOT sound right.
Normally with a random misfire a tune up takes care of it. What has also caused a misfire on those early motors is the popet injectors. They were prone to having problems and have been updated back around 2000 or so. But usually its a cyclinder or two or three or... misfire. All popets going bad is unlikely.
Might try changing the fuel filter and maybe checking pressure. Just the key on pressure should be 60-66psi. While running it may be around 60 and a snap of the throttle will make it rise to 65 or so.

Code po100 & p0300 come up. then I clean throttle body with cleaner, then the van stops missing & run good & light go's out.


P0100 is mass airflow circuit, p0300 is multiple cylinder misfire. Faulty maf sensor is most likely the cause of the misfires.

Very bad engine miss,looking for sparkplug location


Need to take off the plastic on the top of the engine (the plastic box) and the air cleaner hose that goes over to the throttle body. There you will see 6 coil packs. Remove one at a time (2 bolts each), under the coil pack are the spark plugs. I recommend using AC Delco 41-103's for the plugs, will idle better with these. When pushing the coils back on, make sure you hear or feel a little click, too many people install these back on incorrectly, which causes more misfires. If the misfire isn't corrected with the new plugs, check the coils. I also recommend cleaning your throttle body while you're at it, make sure to disconnect the battery while doing this. After it's clean, drive around for 5 miles or so to reset the computer.

If it has a very bad misfire, your check engine light should be on and OR blinking. If it's blinking, don't drive it. You'll probably pull a code of p0300, p0301 & so on which will tell you which cyclinder to focus in on.

When i press accelerator engine is cutting ....


The van may just need a good tune up.

  • Replace the fuel filter
  • Replace the air filter
  • Replace the PVC valve
  • Replace Engine oil and filter
  • Replace the Spark plugs
  • Clean out the Throttle body with throttle body cleaner
  • Clean out the MAF sensor
This should help you get your van running 100% soon. If your on a tight budget, start with Cleaning the throttle body with spraying throttle body cleaner into the throttle body and cleaning up the MAF sensor with MAF sensor cleaner, just follow the instruction on the can. Then replace the PVC valve and add fuel injector cleaner in to the gas tank. This should help your engine running better and then you can do the rest of the work to complete the tune up. Good luck and keep me posted. If you go to Auto Zone, you can get all the things you need and they can scan your van for any DTC codes that may also indicate what issues your engine has.

Misfire on cyclinder


I would check the fuel injector on number 2 cylinder. If the injecter is dirty or not functioning properly it may give you the symptom of an ignition misfire.
