Ok I know everyone is getting tired of my car breaking and me asking questions. I have a problem. My car doesn't start all the time like it is supposed to. I can turn the key off take it out and try again and most of the time it works on the second or third try. The battery is a new Delco 72 month sealed battery, new fuel filter, no problem with spark after I start it, it idles fine right at 750.

After I start it if I try to give it quick throttle, no matter if it's warm or cold, it bogs down and will die if I keep my foot in it. The second I let off it goes right back to idle just fine. Does the same when I am starting foot on gas, no start, let foot off and there she goes just like new. I was thinking it might be a throttle position sensor so I went to my local AAFES parts place and they don't have a TPS nor does anyone in the area. There was a parted out camaro sitting in the back of our craft shop but I missed that by two weeks according to the guys there. I ordered a TPS from the Opel dealer. It will be here Thursday, but if that isn't it I will need some help on this because Chilton sure as hell isn't helping.

This is hopefully the last time I will need this type of advice. I wish my car would quit breaking, it is breaking me. Thanks to everyone on their help with my waterpump problem and I would appreciate a little more help.

Thanks

One more thing, I was trying to reprogram my computer in my car with a Hypertech that already had a VIN# in it and it shut off on me. Would that do it? Am I wasting time and money with the TPS?

You can only reprogram 1 car at a time with Hypertech. I do not think it would cause the problem though!

I am guessing it is a vacuum leak?

Tres when you water pump blew out the bearings was there coolant leaking all over the place. Does your car backfire at all. I've heard some people say if your opti is wet you can use a blow dryer to get rid of the moisture in it. I sent you an e-mail give me a call and I'll help you out with the problem.

The hypertech didn't do anything to your programm. It has to go through a boot up sequence before it can actually programm anything. When you use It. It may help in some areas since it increases spark it may help or it may not. It won't make it worse that's a definate.

I tried hunting down a vaccuum leak with wd-40, I dont know if it works the same way on a fuel injected car as a carbuerated. Normally if you have a leak and you spray WD-40 over the hose the idle will raise a little. There are not that many hoses to check. I dont know what is going on with it. I might have to try and drive it to the craft shop in Schwienfurt and have them hook it up to the diagnostic machine. I am getting no Check Engine light though. I really dont know what it could be. I wont know until I replace the TPS. If that solves the proplem then everything will go as planned. I can pack for PLDC on Thursday and Friday and then come to sembach for the OSL meet. I hope to be there but if my car is acting up there will be no point in me trying to run a 1/4 mile or Auto X.

I had no problems what so ever with the car right after I replaced the waterpump. It was running better than it had in well over 6 months to a year. Matter of fact I did that about a month ago. So I dont think it would all of the sudden start getting that way from moisture. I am still perplexed by my car's timing. Everytime I want to spend a weekend just on my car to take care of little things something else goes wrong. I hope that this part will do it but the dealer wont have it until thursday so I won't know until then. I hope the HPP helps, Ryan is right, it cant hurt.

I have found it only tries to die if it is warm. Does that mean it has to be an emission problem?

Tres

It wasn't the Throttle Position Sensor. Waste of a lot of money at the German dealer. I am thinking it might be the fuel pressure regulator. Normally when you open you gas tank after the car has been running there is built up pressure there, not on my car. Then there is the fact that it seems like it is starving for fuel when I step on the gas. Someone else told me it might be the O2 sensors. I pulled them. Just a little black sut on them but nothing real bad. Any suggestions? Running out of money for random part replacement. I have been trying to catch Randy Enger at work to see if he could listen to it and tell me. No luck yet.

Have you pulled your plugs and wires? Maybe when it warms up, either the resistance in the wires are increasing, are cause a short somewhere. Just a suggestion.

Plugs and wires are relatively new, but I did pull all of the wires off of the left side of the Optispark when I did the waterpump. Will give it a try. I am always open to suggestions.

Hey man the box is on it's way back to you. On another note my opti didn't start acting up until a month and a 1/2 after I blew out my water pump. That's what happened to me it may not be your problem.

I am thinking of taking my car to the dealer on monday and leaving it for the duration of my stay in Graf for PLDC to figure it out. But when you Optispark went out was there any detonation or was it just like it was running out of fuel? I dont really know what it is anymore. Thinking that I am just going to have them diagnose the problem. There is no where else where I can hook it up to a machine but Schweinfurt and I dont think it would make it. Having a problem leaving it there though.

Tres

I wish you the best of luck in finding the problem.... Good Luck...

Going to try the ignition module at Randy Enger's suggestion. He helped me break it down into simple problems. I hope the dealer has it. If not I will find out when I get back from PLDC.
